The Size & Scale Reference shows industry-standard dimensions for board game components, common card sizes, box sizes, token diameters, so you can pick sizes that match what manufacturers expect and what players are used to.
What this page helps you do
Find the standard size for cards, boxes, tokens, dice, etc.
Compare your custom size to standards.
See visual size relationships at a glance.
Open the tool

Browse standards
The tool lists common categories:
Card sizes: Mini USA (41 × 63 mm), Standard USA (56 × 87 mm or "Poker"), Bridge (56 × 89 mm), Tarot (70 × 121 mm), Mini European (45 × 68 mm), Standard European (59 × 92 mm), and more.
Box sizes: Small box (~12 × 12 × 4 cm), Standard box (~28 × 28 × 7 cm), Large box (~30 × 30 × 7 cm), and more.
Tokens: common diameters and thicknesses.
Dice: standard d6 sizes and unusual dice formats.
Punchboard thickness: typical 2 mm, sometimes 1.5 or 2.5.
For each, you see the dimensions and a visual reference scaled to your screen.
Compare a custom size
Enter your own dimensions in the comparison panel. The tool shows your size next to the standards so you can see at a glance:
Is your card "almost a Standard USA"? Probably round to that.
Is your box "between Small and Standard"? Pick one and adjust.
Sticking to standards has practical benefits:
Sleeves: players who sleeve their cards rely on standard sizes.
Manufacturing: non-standard sizes cost more and have longer lead times.
Shelves and storage: boxes that fit standard board game shelf spaces sell better.
When to deviate from standards
Custom sizes make sense when:
The game's mechanic genuinely requires it (e.g. mini cards for compact hand management).
The component is unique enough that no standard fits.
You're making a deluxe / collectible edition where unique presentation is part of the value.
For most prototypes and first-print games, standard sizes save money, time, and headaches.
Tips & common questions
My manufacturer offers different standards. Manufacturers sometimes have their own house standards. Use the closest match here for your prototype, then confirm with the manufacturer for production.
The standards listed don't include my region's preferred size. Open a request via the in-app chat bubble, we add to the reference based on community input.
Can I save my chosen sizes to a game's record? Today, sizes go in the game's Components tab as Notes per component. A dedicated dimensions field is on the roadmap.
Why does 56 × 87 mm appear as both "Standard USA" and "Poker"? They're the same size, different naming conventions across the industry. We list both to make it easy to find.
