How Much Does a Metal Credit Card Weigh? (vs Plastic)

A standard plastic credit card weighs about 6 grams and is 0.76mm thick. A metal credit card weighs far more, usually 14 to 28 grams, with a converted card from us at 28 grams and 0.8mm thick. Both share the same footprint, 85.60 by 53.98mm, so they fit the same wallet slot. The difference you feel is the weight, not the size. 

Here is the full breakdown of how much a credit card weighs and how thick it is, plastic versus metal.

How Much a Credit Card Weighs

Weight is where plastic and metal split apart. Quick reference before the detail:

• Plastic card, about 6 grams
• Converted metal card, 28 grams
• Heaviest metal build, up to 29 grams

Plastic Cards, Around 6 Grams

A standard PVC plastic card weighs roughly 6 grams, light enough to forget in your hand. The ISO 7810 standard sets its size and its thin profile. That lightness is exactly why plastic reads as forgettable at the counter.

Metal Cards, 14 to 28 Grams

Metal cards weigh several times more, commonly 14 to 28 grams depending on the metal and build. A converted card from us sits at 28 grams of stainless steel or brass. The Dual EMV Diamond build runs up to 29 grams, among the heaviest you can carry.

The Tap-and-Pay Card, 19 Grams

A Tap-and-Pay metal card weighs 19 grams, lighter than the full metal build at 28 grams. The reduced weight comes from the construction needed to support contactless payment. It still carries far more presence than plastic.

Bank Metal Cards, For Reference

Among bank-issued metal cards, the Amex Platinum weighs about 17 to 18.5 grams and the Mastercard Black Card about 22 grams. The J.P. Morgan Reserve, made of brass with palladium plating, weighs close to one ounce. Weight varies by issuer and material.

How Thick a Credit Card Is

Thickness barely moves between plastic and metal, because the slot does not.

The Standard, 0.76mm

Every standard card follows ISO 7810, which sets thickness at 0.76mm and the 85.60 by 53.98mm footprint. Plastic and metal both aim for that standard so they fit readers and wallets. The number rarely changes, because the reader slot does not.

Metal at 0.8mm, Still Wallet-Friendly

Our metal cards measure 0.8mm, a hair above the plastic standard, and keep the exact card footprint. That keeps them compatible with normal wallets and most readers. The added substance lives in the material, not the outline.

Why the Weight Matters

A few grams change the whole experience. The jump from plastic to metal shows up in three ways:

• Presence, a card that feels substantial when you set it down
• Durability, metal resists the bending and cracking that wears out plastic
• Perception, weight reads as quality to you and to anyone watching

Heft People Notice

A heavier card lands differently on a counter, and that weight reads as quality. The contrast with light plastic is the entire appeal of going metal. A custom metal card puts that presence in your pocket without touching your account.

Same Function, More Presence

The extra grams change feel, not function. Your chip, swipe, and account work exactly as before, since the conversion moves your real chip into the metal body. You gain presence, and you lose nothing in how the card pays.

The Weight of an Upgrade

A plastic card near 6 grams disappears in your hand, while a metal card at 28 grams announces itself. Both stay the standard size and thickness, so the upgrade costs you no wallet space. The only thing that changes is how the card feels and how it reads. 

Turn your plastic into a custom metal card and feel the difference.

FAQs

How much does a credit card weigh?

A standard plastic credit card weighs about 6 grams. A metal credit card weighs much more, usually 14 to 28 grams, with most converted cards landing near 28 grams. The exact figure depends on the material and build.

How thick is a credit card?

A standard credit card is 0.76mm thick under the ISO 7810 standard, with a footprint of 85.60 by 53.98mm. Metal cards run close to this at about 0.8mm, so they still fit normal wallets and readers. The thickness is nearly identical whether the card is plastic or metal.

How much does a metal credit card weigh?

Most metal credit cards weigh between 14 and 28 grams, several times the weight of plastic. A converted card weighs 28 grams of stainless steel or brass, and the heaviest dual-chip build reaches up to 29 grams. Bank metal cards vary, with the Amex Platinum near 17 to 18.5 grams.

Why are metal credit cards so heavy?

Metal credit cards feel heavy because the body is made of stainless steel, brass, or another metal instead of light PVC plastic. That denser material adds weight while keeping the same card dimensions. The heft is the main reason people choose metal over plastic.

Do metal cards fit in a normal wallet?

Yes. Metal cards keep the standard 85.60 by 53.98mm footprint and a thickness near 0.8mm, so they slide into any normal wallet slot. The weight is higher, but the size is the same as plastic. They fit the way your current card fits.

What is the heaviest metal credit card?

Among bank-issued cards, the J.P. Morgan Reserve is one of the heaviest, made of brass with palladium plating and weighing close to one ounce. The heaviest converted build reaches up to 29 grams with a dual-chip design. Most metal cards land between 14 and 28 grams.
