How to Use the Penny Tile Calculator
Follow these three simple steps to calculate your penny tile, grout, boxes, waste overage, and estimated budget.
Pick penny diameter rounds
Select diameter size (0.75", 1", or 1.5") and pre-mounted sheet sizes in Step 1.
Measure shower floor & drains
Input measurements. Toggle drain cut counts to subtract circle drains and compute mesh slices.
Read sheets & grout volume
Penny layouts create many curved spaces. Plan grout bag counts carefully (budget +30% volume).
How to Calculate Penny Tile Sheets
Since penny rounds are small circular tiles, they are pre-mounted on flexible **12x12 inch mesh sheets** (1.0 square foot per sheet). Your base sheet count will be equal to the total net square footage of the room, rounded up to the next full sheet or box.
Why Penny Tile Needs More Grout
Because penny tiles are circular, they leave substantial open spaces between their outer curves. This increases the total volume of grout required by **30% to 50%** compared to standard square tiles. Ensure you budget grout bag counts accordingly.
Example Penny Tile Calculation
Suppose you want to tile a powder room floor of **32 square feet** using standard penny round sheets with a 12% waste overage:
1. Area = 32 sq ft
2. Coverage per sheet (12x12) = 1.0 sq ft
3. Base sheets count = 32 sheets
4. Add 12% waste = 32 × 1.12 = 35.84 → 36 sheets total
5. If box contains 10 sheets = 4 boxes (rounded up)
Penny Tile FAQs
How many penny tile sheets do I need?▼
If using standard 12x12 inch sheets, divide your square footage by 1.0, then add 10-15% waste allowance.
Does penny tile need more grout?▼
Yes. Due to the circular geometry of the pennies, there are many joint spaces, consuming about 30% more grout than standard mosaic sheets.
Can I use penny tile for a shower floor?▼
Yes, they conform easily to sloped shower pans and offer excellent slip-resistance because of the high density of grout lines.
How do I calculate penny tile around a drain?▼
Always round up your sheet count to the nearest full sheet or box. The mesh backings are cut out manually around floor drains during installation.
