Proportion Wheel and Resolution Calculator

What will be the effective resolution of your image after you scale it up or down? How much scaling does an image need to reach a particular size? Find out with our proportion wheel and resolution calculator.

Proportion Wheel

Functions just like a traditional proportion wheel! Fill in the original dimensions (width and height) and either the reproduction width or reproduction height and click Calculate to receive the final reproduction dimension and the reproduction percentage, or fill in the original dimensions and the reproduction percentage and click Calculate to receive the reproduction width and height.

Effective Resolution Calculator

Fill in the original DPI and the reduction or enlargement percentage and click Calculate to receive the new, modified DPI. This is a good way of determining the effective resolution of your image after it is scaled up or down. For instance a 300 DPI image scaled 200% is not going to output at 300 DPI, but will instead output at an effective resolution of 150 DPI.

Reduction/Enlargement: %

Effective Resolution: DPI
