DICE ART · PRACTICAL GUIDES
How many dice do you need for a mosaic?
The grid controls your dice count. The size of each die controls how large that grid becomes on your wall. Keeping those choices separate helps you plan a build that fits your space and budget.
Count columns × rows
A 31-column by 43-row mosaic contains 1,333 dice. A 50-column by 70-row mosaic contains 3,500. These quantities exclude spares. Each position uses one complete die, regardless of whether its visible face has one pip or six.
The face-by-face breakdown tells you how many dice to orient with each number facing forward. With ordinary dice that have all six faces, you do not need to buy separate one-pip and six-pip dice. Use a consistent dice design throughout the image.
Translate the grid into centimetres
With no gaps, multiply columns by die width for the artwork width, and rows by die width for its height. Divide millimetres by ten to get centimetres. These dimensions exclude the frame.
| Grid | Dice | 10 mm dice | 16 mm dice |
|---|---|---|---|
| 31 × 43 | 1,333 | 31 × 43 cm | 49.6 × 68.8 cm |
| 40 × 50 | 2,000 | 40 × 50 cm | 64 × 80 cm |
| 50 × 70 | 3,500 | 50 × 70 cm | 80 × 112 cm |
Calculated examples with uniform dice and no gaps. Grid: columns × rows. Dimensions: width × height.
Planning a 50 × 70 cm frame
A 50 × 70 grid is not the same as a 50 × 70 cm artwork. With 16 mm dice, a 31 × 43 grid measures 49.6 × 68.8 cm before gaps. This is a near-fit example, not a promise that it fits a frame labelled 50 × 70 cm.
Measure the usable internal opening, depth and any lip covering the artwork. Frame labels may refer to a print size rather than space for a thick dice assembly. Allow for manufacturing tolerances and test a row of your actual dice before cutting a backing board.
Include gaps and spares separately
With gaps, artwork width is columns × die width + (columns − 1) × gap. Use the same formula with rows for height. Keep measurements in the same unit. For example, 31 dice at 16 mm with 0.5 mm gaps span 511 mm, or 51.1 cm.
Spare dice do not change the dimensions. Adding 5% to 1,333 dice gives 1,400 after rounding up. In packs of 100, that means 14 packs. Choose your spare allowance based on availability, defects and how difficult matching replacements would be.
Choose the smallest grid that keeps the subject clear
Compare preview detail levels from a distance. A larger grid helps when it preserves an important feature; it is less useful when it simply adds background. A tighter crop can improve recognition without adding thousands of dice.
Size and weight estimates are planning aids. Confirm the real dice weight and add the backing, frame, adhesive and cover before choosing mounting hardware. Once you have a practical size, save the project and use the placement sheets to keep the build aligned.
