Raw Image Memory Calculator
Raw image bytes equal width × height × channels × bytes per channel. A 1,920 × 1,080 buffer with four one-byte channels occupies 8,294,400 bytes before other memory overhead.
Formula & method
Raw bytes = width × height × channels × bytes/channel; MiB = bytes ÷ 1,048,576.Worked example
| Input | Value |
|---|---|
| Image width | 1,920 px |
| Image height | 1,080 px |
| Channels per pixel | 4 |
| Bytes per channel | 1 B |
| Result | Value |
|---|---|
| Raw buffer payload | 8,294,400 B |
| Raw buffer payload | 7.91015625 MiB |
Compare scenarios
The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.

Assumptions & limits
This estimates raw component storage, not the size of a JPEG, PNG, AVIF or WebP file. Row padding, multiple copies, metadata, colour profiles and GPU allocation may increase actual memory use. Channel and component sizes are user choices.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.
