Tolerances decide if games fit.

The Sizing Principle: Calipers Before Cut

Board game manufacturers operate across different global paper standards. A card advertised as standard CCG may measure 63.0 mm × 88.0 mm from one European printer and 63.5 mm × 88.9 mm from an American print run. If your card sleeves are extruded with only 0.2 mm clearance, the cards will buckle into convex arches that ruin deck shuffling.

Similarly, box inserts manufactured without accounting for 100-micron card sleeves fail instantly. A 100-card deck unsleeved measures roughly 32 mm thick. Sleeved in 100-micron archival polypropylene, that same deck expands to 68 mm thick, requiring more than double the card well depth. Our workshop measures cards with hardened digital vernier calipers under constant temperature conditions before determining tray architecture.

Below is our authoritative dimensional ledger. These specifications govern every sleeve batch and birch insert fabricated at our Portland workbench.

Euro Box Clearances & Vertical Storage

Euro game boxes follow standardized external carton footprints, but internal depths vary wildly depending on board thickness and punchboard layers. Below are the exact tolerances required to ensure boxes close flush with zero lid lift and hold components in place when shelved vertically.

Our insert designs allow a 1.75 mm perimeter expansion buffer around outer walls. This accounts for ambient Portland relative humidity swings without causing box sidewalls to bow outward.

Common Inquiries & Workshop Verification

What if my cards are an unusual size not listed in the matrix?
Bring a sample of 5 to 10 cards to our physical counter at 1500 Southwest 1st Avenue in Portland between 2:00 PM and 10:00 PM. We will measure the width, height, and stack thickness with Mitutoyo digital calipers. If standard sleeves do not match within ±0.5 mm, we will trim or source dedicated non-standard sleeves from archival film stock.

Do your inserts accommodate cards in thick 100-micron matte sleeves?
Yes. Every card well we laser-cut is dimensioned specifically for 100-micron sleeved decks. We allow 0.7 mm of length per card, ensuring a 100-card sleeved deck fits comfortably into a 75 mm deep well without edge binding or pinch points.

Can I verify my game box measurements before requesting an insert?
Yes. Measure the internal length and width of the bottom box tray (not the lid), along with the internal height. Submit these dimensions through our inquiry desk, and our team will confirm compatibility within one business day.
