Getting the size right on a 3D printed MTG deck box is the most common mistake first-time deck box printers make. A box that fits your sleeves on the day you print it can be too tight after the cards expand slightly from shuffling, or too loose if you switch sleeve brands. This guide covers every standard deck configuration, the exact internal dimensions needed for each, sleeve brand behavior, foil card considerations, and which OreKo models are built for which setup.
Standard MTG Deck Configurations
Most Magic: The Gathering decks fall into these configurations based on format and sleeve choice:
| Configuration | Card Count | Sleeve Type | Stack Height (approx.) |
|---|---|---|---|
| Standard 60 unsleeved | 60 | None | ~14mm |
| Standard 60 single sleeve | 60 | Dragon Shield / Ultra Pro Matte | ~20-22mm |
| Standard 60 double sleeve | 60 | Perfect fit inner + outer | ~27-30mm |
| Commander 100 single sleeve | 100 | Dragon Shield / Ultra Pro Matte | ~33-36mm |
| Commander 100 double sleeve | 100 | Perfect fit inner + outer | ~45-48mm |
| Commander 100 + tokens | 100 + 10-20 tokens | Single or double | Add 4-8mm for tokens in same cavity |
Internal Dimension Targets
These are the internal cavity dimensions to target when designing or selecting a deck box. All include 1-2mm clearance on face dimensions for comfortable card movement:
| Configuration | Internal Width | Internal Depth | Internal Height |
|---|---|---|---|
| 60 card unsleeved | 64-65mm | 89-90mm | 17-18mm |
| 60 card single sleeve | 68-69mm | 94-95mm | 22-24mm |
| 60 card double sleeve | 69-70mm | 95-96mm | 28-30mm |
| Commander 100 single sleeve | 68-69mm | 94-95mm | 36-38mm |
| Commander 100 double sleeve | 69-70mm | 95-96mm | 46-48mm |
Sleeve Brand Matters: Thickness Differences
Not all sleeves are the same thickness and this directly affects whether a box fits. These are the brands OreKo deck boxes are tested against:
Dragon Shield Matte: The standard reference for most 3D printed deck box designs. 0.09mm sleeve wall thickness. A 100-card Dragon Shield Matte deck stacks to approximately 33-35mm depending on how tightly shuffled. OreKo boxes are sized for Dragon Shield Mattes.
Ultra Pro Matte / Eclipse: Slightly thinner than Dragon Shield. OreKo boxes fit Ultra Pro Mattes with slightly more clearance than Dragon Shield, which is actually comfortable for play.
KMC Hyper Matte: Slightly thinner than Dragon Shield. Good fit in Dragon Shield-sized boxes.
Dragon Shield Classic (glossy): Slightly thicker than Matte. Can be slightly tight in boxes sized for Matte. Check fit before fully loading the box.
KMC Perfect Fit (inner sleeve): For double-sleeving, these are the most popular inner sleeve. Combined with Dragon Shield Matte outer, the total thickness per card is approximately 0.23mm vs 0.18mm for single Dragon Shield Matte.
Board: when in doubt, measure your deck. Stack your actual sleeved deck, measure the height with a ruler or calipers, and add 2mm to that number to get the minimum internal height you need. This accounts for sleeve variation and leaves comfortable clearance.
The Foil Card Problem
Foil cards are a real sizing issue that many deck box guides ignore entirely.
Foil cards curl. In humid environments (hello, South Florida), foil cards curl more. A deck with 15-20 foils sleeved in Dragon Shield Mattes can be noticeably thicker than the same count of non-foil cards in the same sleeves because the foil cards bow outward, adding height to the stack. In extreme cases with many foils and high humidity, a deck that measured 35mm can stack to 40mm.
If your deck is heavy in foils: measure the actual sleeved deck height and design to that measurement plus 2mm clearance, not to the theoretical calculation based on card count and sleeve thickness. If you’re in South Florida and your foils curl aggressively, store the deck in the box with a flat weight on top overnight — the sleeve compression partially flattens the curl.
The Commander Slot: Design and Purpose
Commander decks are 100 cards, but the Commander card lives in a separate zone during play. Many deck box designs include a dedicated Commander slot: a shallow pocket in the base or lid that holds the Commander card face-up and separately from the main 99-card deck.
Why it matters: It keeps the Commander accessible without digging through the deck. It gives a premium foil, extended art, or special copy of the Commander card its own protected space. At a Commander game night, knowing exactly where your Commander is saves setup time.
The sizing consideration: A single-sleeve Commander slot needs to be at least 69mm wide and 95mm deep internally to accommodate a Dragon Shield Matte sleeved card. The depth in the slot should be 1-2mm to hold the card flat without it rattling around.
The MTG Fallout Deck Box and One Piece Deck Box from OreKo both include a Commander card slot in the base design. The Eldrazi Incursion models are 60-card focused and don’t include a Commander slot.
Token and Dice Storage
Commander decks often come with tokens, counters, and dice that need to travel with the deck. Most serious Commander players want a single carry solution rather than separate bags.
Approaches for deck box token storage:
Tokens in the same cavity. If your token selection is small (5-10 cards), they fit in the same cavity as the deck with a small divider or just loose in the space above the main deck. Add 4-8mm of internal height beyond the deck stack height for this approach. The deck will shift slightly, which is fine.
Separate token compartment in the lid. The most common premium deck box design. A shallow cavity in the lid holds a small stack of tokens face-up, separate from the main deck. This is how the OreKo Commander deck boxes handle tokens in the cap design.
Attached dice tray. A shallow printed tray attached to the outside of the deck box holds d20 life counters and small dice. This adds to the overall footprint but keeps everything organized in one piece.
Lid Design: Friction, Snap, and Magnetic
The lid closure mechanism determines how the box feels in use and how much the design engineering matters for the print tolerances.
Friction fit lid. The most common design. The lid slides over the box body with a small clearance that holds by friction. Tolerance matters most here: 0.3-0.5mm clearance on all sides of the lid-body interface typically gives a satisfying friction closure on PLA printed at standard tolerances. Looser and the lid falls off. Tighter and the lid doesn’t go on. OreKo friction fit lids are designed and tested for this specific tolerance window.
Snap fit. The lid has a small raised lip that clicks over a corresponding recess in the box body. Satisfying audible click on close. Requires PETG for longevity on the snap arm (PLA fatigues after repeated cycling). Less common in deck box designs because the snap geometry adds design complexity.
Magnetic closure. N52 neodymium disc magnets embedded in both the box and lid. Snaps closed automatically with a clean magnetic click. Strong enough to hold in a bag. Easy to open. Requires embedding 6-8mm disc magnets in printed recesses during assembly. The most premium feel closure mechanism available for printed deck boxes.
Printing Tips for Deck Boxes
Deck boxes have specific requirements that differ from general FDM printing:
Layer height: 0.20mm. This is the precision sweet spot. 0.12mm adds significant print time with minimal functional benefit for a structural piece. 0.28mm can affect the dimensional accuracy of the internal cavity enough to change the fit.
Walls: 3 minimum. The walls of a deck box are the structural element. Deck boxes get dropped, jostled in bags, and occasionally sat on. Three walls provide meaningful rigidity without excessive weight.
Infill: 10-15% gyroid. The interior of a deck box wall section doesn’t need high infill. The outer wall geometry provides the rigidity. High infill adds weight and print time without meaningful structural benefit.
Filament: matte PLA. Clean surface quality, minimal layer-line visibility, and a surface that paints well if you want to customize. OreKo deck boxes are photographed in matte PLA.
Logo caps and detail pieces: 100% infill, 0.08-0.12mm layer height. The decorative cap with the logo needs solid infill so the logo relief detail doesn’t have infill pattern bleeding through the thin top layers. Print the cap separately from the box body with these settings.

Frequently Asked Questions: MTG Deck Box Sizing
What internal dimensions do I need for a Commander deck box?
For 100 single-sleeved cards (Dragon Shield Matte): approximately 68-69mm wide, 94-95mm deep, 36-38mm tall internally. For double-sleeved Commander: same face dimensions, increase height to 46-48mm. Add 2mm to your actual measured deck stack height if your deck includes many foil cards.
Will a 60-card deck box fit a Commander deck?
No. A 60-card single-sleeve box has an internal height around 22-24mm. A Commander single-sleeve deck is approximately 33-36mm tall. The deck protrudes by 10-14mm and the lid won’t close.
What is the difference between single sleeve and double sleeve boxes?
Double-sleeving (inner perfect fit + outer sleeve) adds approximately 0.4-0.5mm per card face and 6-8mm to the total stack height compared to single sleeve. A double-sleeve box needs 69-70mm internal width versus 68-69mm for single, and proportionally more height. More detail in the single vs double sleeve sizing guide.
How tight should a 3D printed deck box be?
The deck should slide in and out smoothly with light pressure. No hard pushing to insert. No cards flopping when tilted. 1-2mm of clearance on width and depth beyond the card face dimensions. If the box is slightly tight after printing, lightly sand the interior walls with 180-220 grit in straight strokes to remove 0.1-0.2mm per side.
Why does my deck box fit fine at first but get tight over time?
Cards expand slightly from repeated shuffling. Foil cards in humid environments curl outward, adding stack height. Dragon Shield Matte sleeves break in slightly and can feel different after 50+ shuffles. Size the box to your deck after it’s been sleeved and shuffled several times, not to a freshly sleeved never-shuffled deck.
Do foil cards affect deck box sizing?
Yes, especially in Florida’s humidity. Foil cards curl outward, increasing the effective stack height beyond what card count and sleeve thickness calculations suggest. If your Commander deck has 20+ foils, measure the actual sleeved deck height and add 2mm to get your minimum box height. A box sized to 35mm may not close on a foil-heavy deck that stacks to 38mm.
Can I use a Commander-size box for other card games?
Yes. Standard card games (One Piece TCG, Pokemon, Yu-Gi-Oh) use standard size cards (63x88mm) that fit in any box designed for Magic cards at the same sleeve configuration. One Piece TCG at 50 cards single-sleeved fits in a 60-card single-sleeve box with a few mm of extra height. The One Piece Deck Box from OreKo is specifically designed as a dual-format box for both One Piece TCG and MTG Commander.
