Resolution Scaling Calculator

Work out resolution scaling instantly with clear inputs, formula shown and shareable results.

About Resolution Scaling Calculator

Render scale multiplies both dimensions, so total pixels and therefore GPU load scale with the square of the percentage. A 150% render scale means 2.25 times the pixels, which is why supersampling costs far more performance than the percentage suggests.

Formulas

Scaled dimensions

new dimension = base dimension x render scale

Pixel load

pixel ratio = render scale squared

Worked example

With the default values below, Resolution Scaling Calculator returns Scaled width of 2,880. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Resolution Scaling figure worked out?

new dimension = base dimension x render scale. Render scale multiplies both dimensions, so total pixels and therefore GPU load scale with the square of the percentage.

Why does this matter?

A 150% render scale means 2.25 times the pixels, which is why supersampling costs far more performance than the percentage suggests.

What do I need to enter?

Enter base width, base height, render scale. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
