What size board game box do I need for tabletop games and expansions?

How do I calculate the inside length, width and vertical stack height of a game box?

Always start with the largest flat sheet in your game, which is almost always the folded game board, player mats or rulebook. Measure the folded board length and width, then add 0.125 to 0.1875 inch (1/8 to 3/16 inch) per side to get your inside base Length (L) and Width (W). That perimeter clearance lets the board rest smoothly on the outer ledge of a paperboard trench insert and gives players room to lift the board out without tearing the edges. Next, calculate your inside base Height (H) by summing the vertical stack before tokens are punched. Our design team checks all five layers when building your custom tabletop game boxes so the telescoping lid closes flush to the bottom table surface.

1. Layer 1 - Lower component tray depth: measure the tallest standing deck of cards, dice bag, wooden meeple pile or miniature cavity inside the bottom insert (typically 1.50 to 2.25 inches).
2. Layer 2 - Folded game board thickness: a 2 mm chipboard (gray board) quad-fold board folded into 4 quarters adds roughly 0.35 to 0.40 inch (9 to 10 mm) including the cloth or paper hinge folds.
3. Layer 3 - Unpunched punchboard sheets: multiply the number of token frames by the board caliper (for example, 4 sheets of 2 mm punchboard add 0.32 inch or 8 mm).
4. Layer 4 - Rulebook & player aids: measure the spine thickness of your saddle-stitched rulebook, scenario booklet and reference cards (typically 0.08 to 0.20 inch).
5. Layer 5 - Top breathing room: add 0.125 inch (3 mm) of vertical clearance so the telescoping lid never rides up on the shrink-wrap line.

What are standard board game box sizes by game category?

While CubitPack cuts every two-piece rigid box, folding expansion carton and E-flute mailer to your exact sixteenth of an inch with zero die charges, tabletop retailers and players strongly favor eight recognizable footprints. Using one of these benchmarks makes your game stack cleanly alongside classic titles on store shelves and in home Kallax cubes. When reading the table below, remember that all dimensions are inside base measurements written as Length × Width × Height in inches. On a two-piece telescoping rigid box made from 2 mm (80 pt) chipboard (gray board), the outside footprint of the closed lid will be roughly 0.25 to 0.35 inch wider and longer than the inside base dimensions.

Why do flagship games use 11.5 × 11.5 × 3.0 in square or 12 × 9 × 3 in bookshelf boxes?

Walk into any local game store or look at a board gamer's living room and you will see two dominant box shapes: the 11.5 × 11.5 × 3.0 inch square box and the 12.0 × 9.0 × 3.0 inch rectangular bookshelf box. Both were engineered around two practical constraints: how a large tabletop map folds down, and how four boxes fit into a standard 13.25 × 13.25 inch shelving cube. An inside base of 11.5 × 11.5 inches holds a generous 22 × 22 inch square game board folded into four 11 × 11 inch quarters, and four of these 3-inch-deep custom two-piece rigid boxes slide side by side into a single Kallax cube with half an inch to spare. The 12.0 × 9.0 × 3.0 inch bookshelf format holds a 23 × 17 inch rectangular board folded into four 11.5 × 8.5 inch panels, plus standard 8.5 × 11 inch rulebooks without folding.

How do you size internal insert wells for bare vs sleeved game cards?

One of the most frequent complaints in crowdfunding campaigns is an insert tray that only fits bare cards, forcing players who sleeve their decks to throw the insert away on day one. Standard poker-size game cards measure 2.5 × 3.5 inches (63.5 × 88.9 mm) bare, and bridge-size cards measure 2.25 × 3.5 inches (57 × 89 mm). Once a player slides those poker cards into 100-micron polypropylene sleeves, each card grows to roughly 2.64 × 3.62 inches and the deck stack becomes 60% to 80% thicker. When we engineer a custom cardboard insert or EVA foam tray for your game, we size poker card wells at 2.75 × 3.75 inches and tarot card wells (for 2.75 × 4.75 inch cards) at 3.00 × 5.00 inches, with a half-moon finger scoop on the side wall so sleeved decks lift out cleanly. If your game is purely a card deck without a board, check our dedicated custom playing card boxes guide for tuck-box deck thickness formulas.

How should I size expansion tuck boxes and retail PDQ counter displays?

When releasing faction packs, map expansions or 54-to-110 card booster decks, matching the height or width of your expansion box to your base game creates a cohesive family look on retail shelves. Many publishers size a small two-piece expansion at 7.5 × 5.25 × 1.75 inches (which stacks two-across on top of an 11.5 × 11.5 inch base box) or use a 5.0 × 3.75 × 1.5 inch custom straight tuck end box that drops directly into one of the trench wells inside the core game box. If your pocket game or expansion pack sells at hobby-shop registers inside a custom counter display box, calculate the inside PDQ tray dimensions from the outside dimensions of the individual tuck boxes plus 1/8 inch of total clearance per row.

1. 54-card poker expansion + rules leaflet: 2.625 × 3.625 × 0.875 in straight tuck end carton.
2. 110-card double deck + 1 punchboard sheet: 5.0 × 3.75 × 1.5 in tuck box or small rigid two-piece box.
3. Modular board & miniature faction expansion: 9.0 × 6.0 × 2.0 in two-piece rigid box or tray-and-sleeve box.
4. 12-pack PDQ display tray for 5.0 × 3.75 × 1.5 in boxes (2 rows of 6 upright): 10.375 × 9.50 × 5.0 in tray with fold-up header.

What are the most common board game box sizing mistakes?

Almost every tabletop sizing issue comes from forgetting unpunched punchboard thickness or sizing card wells tight to unsleeved decks. Check these five mistakes before approving your dieline

1. Calculating box height from bagged tokens instead of unpunched punchboard frames, which leaves the lid sitting 0.25 to 0.50 inch high on the store shelf.
2. Sizing poker card wells to 2.55 × 3.55 inches so players who use 2.64 × 3.62 inch protective card sleeves have to discard the insert.
3. Making the folded game board the exact same width as the inside of the box base, leaving no 1/8-inch finger gap to lift the board out.
4. Choosing a 10.5 × 8.0 inch box for an RPG set that includes standard 8.5 × 11 inch US Letter booklets.
5. Confusing outside lid dimensions with inside base dimensions on a 2 mm chipboard (gray board) telescoping box (the outside lid is roughly 0.30 inch larger).
