Sprite Atlas Capacity Calculator
Plan a grid of sprites in a texture with padding around each cell.
Your inputs
Calculation results
Formula & assumptions
Capacity = floor(atlas width/(sprite width+2padding)) × floor(atlas height/(sprite height+2padding)).
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Sprite Atlas Capacity Calculator
Plan a grid of sprites in a texture with padding around each cell.
- Enter atlas width, atlas height, sprite width, sprite height, padding per edge using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Atlas width: 2048 pixels Atlas height: 2048 pixels Sprite width: 64 pixels Sprite height: 64 pixels Padding per edge: 2 pixels Columns: 30 Rows: 30 Sprite capacity: 900 RGBA atlas memory · MiB: 16
Questions & answers
What does Sprite Atlas Capacity Calculator calculate?
Plan a grid of sprites in a texture with padding around each cell.
Which units should I enter?
Atlas width uses pixels. Atlas height uses pixels. Sprite width uses pixels. Sprite height uses pixels. Padding per edge uses pixels. Convert values to these units before calculating.
Which formula does it use?
Capacity = floor(atlas width/(sprite width+2padding)) × floor(atlas height/(sprite height+2padding)).
What does the included example show?
Atlas width: 2048 pixels; Atlas height: 2048 pixels; Sprite width: 64 pixels; Sprite height: 64 pixels; Padding per edge: 2 pixels. Result: Columns = 30; Rows = 30; Sprite capacity = 900; RGBA atlas memory · MiB = 16.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
