Why Sleeve Size Matters Before You Print
Ordering a deck box before knowing your sleeve setup is one of the most common TCG mistakes. The wrong size means cards that rattle, lids that won’t close, or a box so tight you damage sleeves pulling cards out.
For 3D printed deck boxes, sleeve size is baked into the design. You need to know your sleeve situation before you download and print. Here is the complete breakdown.
Unsleeved
A standard TCG card (One Piece, MTG, Pokemon, etc.) measures 63 x 88mm. Without sleeves, cards are thin and stack very tightly. Most competitive players sleeve at minimum, so unsleeved boxes are mostly for casual use or storage.
Single Sleeved
One outer sleeve around each card. The most common setup for everyday play. A standard outer sleeve adds approximately 2mm to the width and 2-3mm to the height, bringing a typical single-sleeved card to approximately 65-66 x 90-91mm. This is the most widely supported deck box format.
Double Sleeved
An inner sleeve (perfect fit) plus an outer sleeve. This is the preferred setup for valuable or tournament-used cards. The inner sleeve seals the card and the outer sleeve takes the wear. Double-sleeved cards run approximately 68-69 x 93-94mm, noticeably larger than single-sleeved. You need a box specifically designed for double sleeve.
Sleeve Size Reference Table
| Configuration | Width | Height | Notes |
| Unsleeved | 63mm | 88mm | Standard card dimensions |
| Single Sleeve (standard) | ~65-66mm | ~90-91mm | Most common format. Dragon Shield, KMC, Ultra Pro |
| Double Sleeve | ~68-69mm | ~93-94mm | Inner + outer sleeve. Most protection, largest footprint |
How OreKo Deck Boxes Handle Sleeve Size
The OreKo deck maker set for One Piece Card Game is designed for single-sleeved decks as the primary configuration. The MTG Modern Horizons 3 Eldrazi deck box is available in two distinct versions: standard (single sleeve) and dual sleeve.
Always check the product listing before printing. The listing specifies which sleeve configuration the box is designed for. If you are between sizes or use particularly thick sleeves, print a test cap at 101% scale to check fit before committing to a full print.
Adjusting Fit with Scale
Even with the right version, slight variations in sleeve brands can cause fit issues. Here is how to adjust:
Lid too tight: Reprint at 99% scale or reduce the lid by 0.2-0.5mm. For most slicer tools, scaling down by 1-2% on the lid alone (not the body) solves most tightness issues.
Too much rattle: Reprint at 101% scale. Or add a thin foam insert at the bottom of the box to raise the cards slightly.
Cards don’t fit at all: You likely have the wrong version. If you have double-sleeved cards, you need the double sleeve version of the file.
First print tip: Print the lid only first, test the fit with your sleeved deck, then print the body if the fit is correct. Saves filament and time.
