Cardwright Open the studio

Guides for card game designers

Free, specific, no fluff — the print specs, alignment fixes, and tool comparisons we wish existed when we started building card games. Written by the team behind Cardwright, usable whether you ever open the tool or not.

How to playtest a card game solo (with an AI opponent)

The opponent bottleneck kills iteration. What solo playtesting can and can't tell you — and how the Cardwright Table's AI opponent changes the loop.

Why your double-sided cards don't line up (and how to fix it)

Duplex misalignment is the single most common print-and-play complaint. The actual cause, and the two reliable fixes: gutter-fold and printer calibration.

Print bleed and safe zones, explained with real numbers

What bleed actually is, why your cards need it, and the exact millimeter and pixel measurements print services expect — not vague advice.

Tabletop Simulator custom deck setup, the complete guide

The exact grid, resolution cap, and hidden-card-slot rules TTS expects for a custom deck — and every place first-timers get it wrong.

Card-making tools compared: nanDECK, Dextrous, component.studio, and more

An honest look at what each tool is actually good at, what it costs, and who it's really for — including where we think Cardwright fits and where it doesn't.

Card sizes for printing — every standard dimension

Poker, bridge, tarot, mini, and square — exact millimeter, inch, and 300 DPI pixel dimensions, bleed sizes, and how many fit on a sheet. A precise reference for each size.
