Board Game Storage Calculator – How Many Inches of Shelf?

Measure your board game box in three dimensions: Length (longest side of the front face), Width (shorter side of the front face), and Thickness (the narrow spine edge). For vertical storage, the thickness is the most important—it determines how many inches of shelf each game consumes. Use a tape measure and round to the nearest 0.1 inch for accuracy.

Vertical storage (spine out) is generally recommended by most board game enthusiasts. It prevents box lids from sagging under weight, makes it easier to pull out individual games without disturbing the stack, and often uses shelf space more efficiently. Horizontal stacking can cause box bottoms to bow over time, especially for heavier games. However, some games with lots of loose components (like inserts with many tokens) may fare better horizontally. For the best of both worlds, store vertically and use baggies or inserts to keep components organized.

An IKEA Kallax cubby has internal dimensions of approximately 13″ × 13″ × 15″ deep (33 × 33 × 38 cm). Most standard board games (like Ticket to Ride, Catan, Wingspan) fit perfectly in a single Kallax cube when stored vertically—you can typically fit 4–6 standard-sized games per cubby. A 2×4 Kallax unit (8 cubbies) can hold roughly 30–50 games depending on box sizes. Larger boxes like Gloomhaven (16.3″ long) will not fit in a Kallax cube vertically and need to be stored on top or in a different shelf unit.

There's no single "standard," but the most common board game box dimensions fall into these ranges: Small card games (6–7″ × 4–5″ × 1–2″), Medium Euro games (12″ × 9″ × 2–3″ like Catan, Pandemic), Large square boxes (12″ × 12″ × 3″ like Ticket to Ride, Wingspan), and Extra-large boxes (14–16″ × 11–12″ × 5–8″ like Gloomhaven, Scythe). Knowing your mix of box sizes helps when planning shelving—this calculator does exactly that.

For most board games stored vertically, a shelf depth of 11–12 inches is sufficient for standard boxes. If you have larger games (like Scythe at 14.5″ or Gloomhaven at 16.3″), you'll need a shelf depth of at least 15–17 inches to prevent boxes from protruding. IKEA Kallax shelves are ~15″ deep, which accommodates most games except the very largest. The Billy bookcase is about 11″ deep—fine for standard sizes but too shallow for oversized boxes. Our calculator shows the minimum shelf depth your collection requires.

When done properly, vertical storage does not damage components. The key is to use well-fitting inserts, baggies for loose pieces, or aftermarket organizers. Many modern games come with inserts designed for vertical storage. For older games or those with flimsy inserts, you can add foam blocks or 3D-printed supports to keep everything in place. Some collectors use rubber bands (sparingly—they can degrade) or Velcro straps to keep boxes tightly closed. The benefits of vertical storage (easier access, no lid sag) usually outweigh these minor considerations.

For vertical storage, simply add up the thickness of every game box—that's your total shelf length in inches. For example, 10 games each 3″ thick = 30″ of shelf space. For face-out display, add up the widths instead. Our calculator does this automatically and also accounts for the maximum depth and height clearance your collection needs. Add 5–10% extra for breathing room and future acquisitions!

The IKEA Kallax is by far the most popular choice—it's affordable, sturdy, and its 13″ cube dimensions fit most board games perfectly. Other excellent options include: IKEA Billy (deeper variant with 15″ shelves, great for adjustable spacing), Better Homes & Gardens Cube Storage (similar to Kallax, available at Walmart), custom built-in shelving with 14–16″ depth for maximum flexibility, and heavy-duty metal garage shelving for very large collections (holds more weight per shelf). Always check shelf depth and weight capacity before purchasing.
