Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Halve each dimension with floor and clamp at one, retaining at most the entered number of levels.
Level bytes=ceil(width/block width)×ceil(height/block height)×block bytes×layers
Worked example
A 4×4 uncompressed four-byte texture has levels of 64,16,4 bytes: 84 bytes total.
Assumptions and input details
Independent 2D images; no row alignment, tiling, 3D depth, driver metadata, residency or additional copies. Minimum compressed storage is one block per nonempty level.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Estimate media file size from duration and average audio/video bitrates, or solve the video bitrate available under a file-size limit.
Compare bits and bytes using clearly separated decimal and binary prefixes.
Count equal-size sprites that fit an atlas with explicit outer margins and inter-sprite gutters.
