Texture Memory Calculator
Estimate uncompressed GPU texture memory with an optional complete mip chain.
Your inputs
Calculation results
Formula & assumptions
Base bytes = width × height × bytes per pixel; mip dimensions halve with floor until 1×1.
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 Texture Memory Calculator
Estimate uncompressed GPU texture memory with an optional complete mip chain.
- Enter texture width, texture height, bytes per pixel, textures 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
Texture width: 2048 pixels Texture height: 2048 pixels Bytes per pixel: 4 bytes Textures: 10 textures Base textures · MiB: 160 With full mip chain · MiB: 213.33332
Questions & answers
What does Texture Memory Calculator calculate?
Estimate uncompressed GPU texture memory with an optional complete mip chain.
Which units should I enter?
Texture width uses pixels. Texture height uses pixels. Bytes per pixel uses bytes. Textures uses textures. Convert values to these units before calculating.
Which formula does it use?
Base bytes = width × height × bytes per pixel; mip dimensions halve with floor until 1×1.
What does the included example show?
Texture width: 2048 pixels; Texture height: 2048 pixels; Bytes per pixel: 4 bytes; Textures: 10 textures. Result: Base textures · MiB = 160; With full mip chain · MiB = 213.33332.
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.
