Stretched Resolution Calculator

Frequently Asked Questions

Why do player models look bigger on stretched resolution?

The narrow render buffer is widened to fill the screen, so every model gains horizontal width by the stretch factor. This can make targets easier to track, at the cost of image sharpness.

Does stretched resolution actually help aim?

It is largely preference. Some find wider models easier to track; others lose precision from the blur. Test both and keep whichever you can be consistent with.

Will the FOV really change?

Only if the game scales FOV with aspect ratio (Hor+). Titles that lock vertical FOV may crop instead of widening - verify in-game.

Is stretched resolution allowed in competitive play?

It is a display setting allowed in essentially all competitive titles. Anti-aliasing and clarity suffer at non-native resolutions, so weigh the readability gain against the visual cost.

What is the difference between GPU scaling and display scaling?

GPU scaling happens in the graphics card before the signal reaches the monitor. Display scaling happens in the monitor's scaler. Only the component doing the scaling determines whether the buffer is stretched or letterboxed.

How It Works

Many competitive players run a non-native "stretched" resolution - for example rendering 1280x960 (a 4:3 buffer) and letting a 16:9 monitor scale it to fill the screen. The graphics card draws a narrow buffer, then the display stretches it horizontally, which makes player models appear visibly wider and, depending on the game's FOV scaling, slightly changes how much of the world you see.

This tool computes the render aspect ratio, the display aspect ratio, the resulting horizontal stretch factor (how much wider every pixel becomes), and an estimate of the effective horizontal FOV after the stretch.

Stretch factor = displayAR ÷ renderAR. New half-FOV = arctan(tan(oldHalfFOV) × stretchFactor). Effective FOV = new half-FOV × 2. This uses the tangent-based (Hor+) FOV scaling relationship used by most modern engines.

Use Cases

Stretched resolution calculations are relevant for competitive PC gamers tweaking their setup:

Calculating the exact stretch factor before committing to a new resolution to understand how much wider models will appear.

Checking the effective FOV change so you can compensate your sensitivity if the game scales FOV with aspect ratio.

Comparing different stretched resolutions (1280x960, 1440x1080, 1024x768) to find the stretch sweet spot for your style.

Verifying that your GPU scaling setting is actually stretching rather than letterboxing, by confirming the expected render and display ratios.

Understanding the trade-off between model width advantage and image quality reduction at non-native resolutions.

Tips

Verify GPU scaling settings: "Maintain aspect ratio" in the driver adds black bars and removes the stretch entirely. You need full-screen/aspect-ratio-off scaling for the buffer to actually stretch.

Vert- games may crop instead of widening: Some engines lock vertical FOV rather than horizontal. Confirm which axis your game uses before trusting the FOV figure from this tool.

Stretched is preference, not a pure advantage: Horizontal motion is also faster and image clarity drops at non-native scaling. Test both and keep whichever you can be more consistent with.

Stretch can interact with ADS sensitivity: If the game scales ADS FOV differently, your scoped sensitivity may feel off after switching - check and adjust separately.

Common stretched resolutions: 1280x960 and 1440x1080 are the most popular 4:3 options. 1024x768 gives a more aggressive stretch. 1280x1024 (5:4) gives a milder stretch than 4:3.

FAQ

Why do player models look bigger on stretched resolution?

The narrow render buffer is widened to fill the screen, so every model gains horizontal width by the stretch factor. This can make targets easier to track at medium range, at the cost of image sharpness and faster horizontal mouse travel.

Does stretched resolution actually help aim?

It is largely preference and habit. Some players find the wider models easier to track; others lose precision from the blur and altered sensitivity feel. Test both and keep whichever you can be consistent with.

Will the FOV really change?

Only if the game scales FOV with aspect ratio (Hor+). Titles that lock vertical FOV may crop instead of widening, so verify in-game rather than trusting a single formula.

Is stretched resolution allowed in competitive play?

It is a display setting, not a cheat, and is allowed in essentially all competitive titles. However, anti-aliasing and clarity suffer at non-native resolutions - weigh the readability gain against the visual cost.

What is the difference between GPU scaling and display scaling?

GPU scaling happens in the graphics card before the signal reaches the monitor. Display scaling happens in the monitor's scaler chip. Only the component doing the scaling determines whether the buffer is stretched or letterboxed.
