Review the method below for assumptions and conventions.

How to use this tool

  1. Enter width, height, bits per pixel.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

Input reference and sample values

Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.

InputFormat and unitsSample
WidthWhole numbers only. Minimum: 1. Maximum: 100000.6000
HeightWhole numbers only. Minimum: 1. Maximum: 100000.4000
Bits per pixelWhole numbers only. Minimum: 1. Maximum: 128.24

Result for these sample inputs

68.6645508 MiB

Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.

The method, explained

Bytes = ceil(width × height × bits per pixel/8). MiB = bytes/1,048,576.

A WORKED EXAMPLE

Using width = 6000, height = 4000, bits per pixel = 24, the result is 68.6645508 MiB. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Excludes row padding, metadata, file headers and compression. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.
