Custom Enamel Pin Thickness Guide: 1.2mm vs 1.5mm vs 2mm

Enamel pin thickness affects more than the side profile of the finished product. It can influence weight, hand feel, structural rigidity, perceived value, post attachment, wearing comfort and production cost.

For many standard custom enamel pin projects, around 1.5mm is a practical thickness to consider, while thinner or thicker specifications may be better depending on the pin size, design, intended weight and product positioning.

A thicker pin is not automatically a higher-quality pin. The correct specification should balance the finished pin size, base metal thickness, weight-to-size ratio, attachment system and intended use.

This guide compares 1.2mm, 1.5mm, 1.8mm and 2.0mm custom enamel pin thicknesses and explains how to choose an appropriate specification before production.

What Thickness Should an Enamel Pin Be?

The best enamel pin thickness depends on the finished size, artwork, desired weight, intended use and backing configuration rather than one universal measurement.

What Does Enamel Pin Thickness Actually Mean?

Enamel pin thickness generally refers to the thickness of the metal body or base metal used to form the finished pin.

It should not be confused with the width or height of the pin.

For example, a pin may be:

The 32mm and 28mm measurements describe the face dimensions, while 1.5mm describes the metal body's thickness.

What Is the Difference Between 1.2mm, 1.5mm and 2mm Enamel Pins?

The main difference is the amount of metal in the body of the pin, which can affect weight, side profile, rigidity, hand feel and production cost.

Increasing thickness does not necessarily change the artwork on the front. Instead, it changes the physical construction of the product.

That means two pins can use exactly the same artwork and face dimensions but feel noticeably different when produced with different metal thicknesses.

Is 1.2mm Thick Enough for an Enamel Pin?

Yes, 1.2mm can be suitable for some small or lightweight enamel pin designs where a thinner metal profile is appropriate.

It may be considered for:

• Small logo pins
• Simple promotional pins
• Lightweight merchandise
• Projects where reducing weight is useful
• Designs that do not require a particularly substantial side profile

However, thickness should never be selected only to reduce material cost.

For larger or heavier designs, the relationship between pin size and metal thickness should be reviewed before production.

Is 1.5mm a Good Thickness for Enamel Pins?

Yes. Around 1.5mm can provide a practical balance of weight, structural feel and manufacturability for many standard custom enamel pin projects.

It can work well for:

• Artist merchandise
• Brand merchandise
• Corporate pins
• Event pins
• Organization pins
• Kickstarter merchandise
• Collector designs of moderate size

However, it should be treated as a useful starting point rather than a universal manufacturing standard.

A small minimalist pin may not need the same thickness as a large premium collector design.

When Should You Choose a 1.8mm Enamel Pin?

A 1.8mm thickness can be useful when a design needs a more substantial metal profile without moving directly to a 2mm specification.

It may suit:

• Larger enamel pins
• Premium merchandise
• Collector designs
• Corporate recognition pieces
• Products where hand feel is important
• Designs intended to feel more substantial than lightweight promotional pins

At this stage, the finished weight becomes increasingly important because a larger pin combined with increased thickness can create a significantly heavier product.

When Should You Choose a 2mm Enamel Pin?

A 2mm metal thickness is worth considering when the product is intentionally designed to feel substantial, premium or structurally robust.

Potential applications include:

• Large collector pins
• Premium limited editions
• Oversized enamel pins
• Commemorative products
• High-perceived-value merchandise
• Specialty branded products

But 2mm should not automatically be selected just because the product is positioned as premium.

A thicker metal body also increases weight, which may affect:

• Wearing comfort
• Post attachment
• Pin rotation
• Backing configuration
• Packaging
• Shipping weight
• Production cost

Does a Thicker Enamel Pin Mean Better Quality?

No. A thicker enamel pin can feel heavier and more substantial, but thickness alone does not determine product quality.

Finished quality can also depend on:

• Base metal quality
• Tooling accuracy
• Metal line definition
• Enamel application
• Color accuracy
• Surface polishing
• Plating consistency
• Post attachment
• Edge finishing
• Quality inspection

Thickness should therefore be treated as a product specification, not a standalone quality score.

What Is Perceived Value in Custom Pin Manufacturing?

Perceived value is the customer's impression of a product's quality and worth based on factors such as weight, finish, detail, presentation and hand feel.

A thicker metal body can contribute to perceived value because it may make the pin feel more substantial when held.

However, perceived value is created by the complete product:

For premium merchandise, increasing thickness may help, but it should be balanced against comfort, cost and intended use.

What Is Weight-to-Size Ratio?

Weight-to-size ratio describes how heavy a finished pin feels relative to its physical dimensions.

Two pins with the same width and height can feel very different if one uses a thinner metal body and the other uses a thicker one.

Likewise, a 2mm specification on a small pin does not create the same wearing experience as 2mm on a large 50mm collector pin.

Does Pin Thickness Affect Durability?

Thickness can contribute to structural rigidity, but durability depends on the complete construction rather than metal thickness alone.

Factors that affect durability can include:

• Base metal
• Pin dimensions
• Overall geometry
• Metal thickness
• Post attachment
• Plating
• Enamel process
• How the product is worn and handled

A thicker body may provide more rigidity, but increasing thickness does not compensate for poor tooling, weak attachment hardware or unsuitable design specifications.

What Is Structural Rigidity?

Structural rigidity describes how resistant the metal body is to unwanted flexing or deformation under normal handling.

Rigidity can be influenced by:

• Metal type
• Metal thickness
• Overall pin size
• Shape
• Cut-outs
• Long narrow sections
• Internal geometry

A large pin with long narrow extensions may behave differently from a compact circular pin even when both use the same thickness.

Should a Large Enamel Pin Be Thicker?

Not automatically. Large pins may benefit from additional thickness in some designs, but the correct specification should be based on size, shape, material, weight target and intended use.

The key relationship is:

For example, increasing both the width and thickness can create a heavier product that may require more attention to:

• Post placement
• Single vs dual posts
• Clutch selection
• Anti-rotation
• Wearing stability

This is why size and thickness should be reviewed together rather than selected independently.

See our Custom Enamel Pin Size Guide for more information about choosing finished dimensions.

Does a Thicker Pin Need Two Posts?

Thickness alone does not determine whether an enamel pin needs two posts; finished size, total weight, shape and center of gravity are more important.

A small 2mm pin may still work well with one post, while a long or asymmetrical 1.5mm design may benefit from two.

For backing selection, see our Enamel Pin Backings Guide.

How Does Thickness Affect Post Attachment?

The metal body and post system must work together as one mechanical structure, so the attachment method should be appropriate for the finished product's weight and geometry.

During production review, manufacturers may consider:

• Number of posts
• Post position
• Finished product weight
• Pin dimensions
• Metal body
• Backing type
• Expected wearing conditions

This becomes more important as the product becomes larger or heavier.

How Does Pin Thickness Affect Wearing Comfort?

A thicker pin can feel more substantial, but additional thickness may also increase weight, which can affect how the product sits on lightweight clothing.

The wearing experience depends on the complete specification:

For a pin intended mainly for display or collector packaging, additional weight may be desirable.

For a pin intended for daily wear on lightweight clothing, excessive weight may be less practical.

Does Thickness Affect Enamel Pin Cost?

Yes. Increasing metal thickness can increase material usage and therefore may increase production cost, especially when combined with a larger finished size.

However, thickness is only one cost variable.

Final pricing can also depend on:

• Pin size
• Order quantity
• Base metal
• Hard or soft enamel
• Artwork complexity
• Number of colors
• Plating
• Printing
• Special effects
• Backing hardware
• Packaging

See our Custom Pin Pricing Guide for additional pricing factors.

Is It Worth Paying More for a Thicker Enamel Pin?

It can be worth increasing thickness when the added weight and side profile support the intended product positioning, but extra thickness should provide a clear design or merchandising benefit.

Consider additional thickness when:

• The product is positioned as premium merchandise
• A more substantial hand feel is desired
• The pin is a collector piece
• The design is relatively large
• The side profile is part of the intended aesthetic

Avoid increasing thickness only because “more metal sounds better.”

A properly specified 1.5mm product can be more appropriate than a 2mm product that is unnecessarily heavy.

Does Hard Enamel or Soft Enamel Require a Different Thickness?

Hard enamel and soft enamel are primarily different surface and filling processes; the appropriate metal thickness should still be selected according to the complete product specification.

The key visual distinction is:

• Hard Enamel: smooth polished surface with enamel finished level with the metal lines.
• Soft Enamel: raised metal lines with recessed enamel areas.

Thickness and enamel type should therefore be treated as separate but related decisions.

See our Hard Enamel vs Soft Enamel Pins Guide for a detailed comparison.

Does Base Metal Affect Thickness Selection?

Yes. The selected base metal and manufacturing process can influence how thickness, weight, detail and structure should be specified.

Depending on the product and production method, custom metal products may use materials such as:

• Iron
• Brass
• Zinc alloy
• Other suitable metal substrates

Material selection should consider:

• Artwork geometry
• Desired relief
• Finished size
• Weight target
• Manufacturing process
• Surface finish
• Budget

What Is the Difference Between Base Metal Thickness and Finished Thickness?

Base metal thickness refers to the metal body's nominal specification, while the finished product includes additional manufacturing processes such as plating and enamel application.

For purchasing and manufacturing discussions, it is important to confirm what a stated thickness measurement actually refers to.

For this reason, technical drawings and production specifications should clearly identify the intended measurement.

What Is Metal Gauge?

Metal gauge is a general term used to describe metal thickness, although custom pin factories commonly communicate pin specifications directly in millimeters.

For enamel pin purchasing, specifications such as:

are clearer than relying on an ambiguous gauge description.

Using millimeters also makes it easier to compare technical drawings, quotations and production specifications.

What Is an Edge Profile?

The edge profile is the visible side surface of the finished metal product and becomes more visually noticeable as thickness increases.

A thicker pin can create a more substantial edge when viewed from the side.

Edge appearance can be influenced by:

• Metal thickness
• Product shape
• Plating
• Polishing
• Relief
• Manufacturing process

How Does Thickness Affect Premium Merchandise?

For premium merchandise, thickness can contribute to a more substantial physical experience, but it should be combined with appropriate finishing, plating and packaging.

A premium product is better considered as a complete system:

For example, a thicker collector pin presented on a custom backing card or in a gift box can create a very different impression from the same pin supplied loose in basic packaging.

See our Custom Packaging Options when planning premium merchandise.

How Should Thickness Be Chosen for Corporate Pins?

Corporate pins should balance professional appearance, wearing comfort and product positioning rather than simply maximizing metal thickness.

Consider:

• Whether employees will wear the pin daily
• Uniform or garment type
• Logo dimensions
• Pin weight
• Backing type
• Presentation packaging
• Whether the product is promotional or commemorative

A lightweight promotional pin and a premium executive recognition pin may require different specifications even if both use the same corporate logo.

How Should Thickness Be Chosen for Artist and Kickstarter Pins?

Artist and Kickstarter pins should use a thickness that supports the artwork, reward tier, selling price and desired collector experience.

For creator merchandise, ask:

• Is this an entry-level reward or premium reward?
• How large is the artwork?
• Will customers wear or display the pin?
• Is the product part of a set?
• Will custom packaging be included?
• How much finished weight is appropriate?

A premium collector reward may benefit from a more substantial construction, while an entry-level merchandise pin may be better optimized for weight and budget.

How Does Thickness Affect Shipping and Packaging?

Thickness can indirectly affect shipping and packaging because increasing the metal volume increases finished product weight.

For a small order, the difference may be modest. For hundreds or thousands of pieces, small changes in individual product weight can accumulate across the shipment.

Packaging should also provide enough space for:

• The pin body
• Pin posts
• Clutches
• Backing cards
• Protective materials
• Gift boxes where required

This is especially relevant for large, thick collector pins and multi-pin sets.

What Is Production Tolerance for Pin Thickness?

Production tolerance refers to the small acceptable variation that can occur when a specified digital measurement is manufactured as a physical metal product.

A technical specification should not assume that every physical piece can be interpreted as mathematically identical to an infinitely precise digital model.

Manufacturing can involve:

• Tooling
• Metal forming
• Polishing
• Plating
• Enamel application
• Assembly

This is why production specifications should focus on functional and visual requirements rather than unnecessary decimal precision.

What Is a Manufacturability Review?

A manufacturability review evaluates whether the proposed size, thickness, artwork, metal structure and backing configuration work together as a practical physical product.

Before production, the review can consider:

• Finished pin size
• Base metal thickness
• Artwork complexity
• Metal line structure
• Enamel areas
• Expected finished weight
• Post placement
• Single vs dual posts
• Backing type
• Packaging

Do You Need to Know the Exact Thickness Before Requesting a Quote?

Enamel Pin Thickness Selection Checklist

Before approving a thickness specification, evaluate the complete physical product rather than the metal depth alone.

Frequently Asked Questions

How thick should an enamel pin be?

The ideal enamel pin thickness depends on the pin's size, shape, desired weight, intended use and backing configuration. Around 1.5mm can be a practical reference point for many standard projects, but it is not a universal requirement.

Is 1.5mm thick enough for an enamel pin?

Yes. Approximately 1.5mm can provide a balanced metal profile for many custom enamel pin projects, depending on the design and finished size.

Is 1.2mm too thin for an enamel pin?

Not necessarily. A 1.2mm specification can be suitable for smaller or lightweight designs when a thinner profile is appropriate.

Are 2mm enamel pins better?

Not automatically. A 2mm pin may feel heavier and more substantial, but product quality also depends on material, tooling, enamel, polishing, plating, assembly and quality control.

Does enamel pin thickness affect durability?

Thickness can contribute to structural rigidity, but durability depends on the complete construction, including metal, geometry, post attachment, plating and intended use.

Does a thicker enamel pin feel more premium?

It can. Additional thickness and weight may increase perceived value and hand feel, but finishing, plating, artwork quality and packaging also contribute to the premium experience.

Does pin thickness affect production cost?

Yes. Increasing thickness generally increases metal usage and may increase production cost, especially when combined with larger finished dimensions.

Should a large enamel pin be thicker?

Not automatically. Large pins should be evaluated according to size, shape, material, finished weight, structural requirements and intended use before increasing thickness.

Does a 2mm enamel pin need two posts?

Not necessarily. The need for two posts depends more on total size, weight, shape, center of gravity and wearing stability than thickness alone.

What is the difference between base metal thickness and finished thickness?

Base metal thickness describes the nominal metal body specification, while finished thickness refers to the physical depth of the completed product after the relevant manufacturing processes.

Can PixelToPin recommend the right enamel pin thickness?

Yes. Send your artwork, finished size, quantity and intended use, and PixelToPin can review the thickness, weight, backing and manufacturability requirements before production.
