Resolution Scale Calculator

Scaling Image Resolution

Games, video editors, and design tools often let you render at a percentage of native resolution. This calculator shows the resulting width and height while keeping the original aspect ratio intact.

Scaled Resolution Formula

$$\text{Scaled Width} = \text{Original Width} \times \frac{\text{Scale \%}}{100}$$ $$\text{Scaled Height} = \text{Original Height} \times \frac{\text{Scale \%}}{100}$$

Pixel count scales with the square of the scale factor. At 75% resolution, pixel count drops to 56.25% of the original (0.75² = 0.5625). Related tools: Image Ratio Calculator and Pixels to Print Size Calculator.

Frequently Asked Questions

Does scaling change aspect ratio?

No. Both width and height are multiplied by the same scale factor, so the aspect ratio stays the same.

Why does pixel count drop faster than scale percent?

Pixels are two-dimensional. Halving each dimension quarters the total pixel count.

What is a common game render scale?

Many games use 75% or 80% render scale for a performance boost with modest visual impact on modern displays.

Are results rounded?

Yes. Scaled width and height are rounded to whole pixels, which is standard for display resolutions.

Can I upscale above 100%?

Yes. Enter a scale above 100% to see supersampled dimensions and the increased pixel count.
