What this means for you

By playing 4:3 stretched, player models will visually appear 33% wider on your screen, making them easier to spot. However, your horizontal mouse movement will visually feel much faster, and you will lose peripheral vision on the sides.

Missing Dimension Calculator

Instantly calculate a missing resolution width or height based on a target aspect ratio (e.g. 16:9, 21:9).

About Stretched Resolutions

In competitive shooters like CS2 and Valorant, many professional players opt to play on "Stretched" resolutions (e.g., forcing a 1280x960 4:3 resolution to stretch across a standard 1920x1080 16:9 monitor). This technique distorts the image horizontally, effectively making everything on screen appear wider.

This advanced Aspect Ratio Calculator helps you mathematically visualize the exact trade-off: You gain physically larger target models on your screen, but you immediately lose peripheral field of view (FOV) and your horizontal mouse movements will perceptually feel significantly faster.

How to Use the Aspect Ratio Calculator

  1. Enter a custom Width and Height resolution or click a popular preset button (like 1280x960).
  2. The tool instantly calculates the core mathematical aspect ratio and determines pixel loss compared to native 1080p.
  3. Toggle the Scaling Mode to "Stretched (Full Screen)" to see exactly how the image, crosshair, and player models distort on a standard 16:9 monitor.
  4. Select your Target Game to calculate specific Engine FOV impacts and copy the exact m_yaw sensitivity fixes required.

Common Competitive Resolutions

  • 1920x1080 (16:9): Native standard. Offers the best visual clarity and the widest horizontal FOV. Standard for modern games like Valorant and Overwatch.
  • 1280x960 (4:3): The absolute "GOAT" CS2 resolution. Models look significantly wider, making holding tight angles visually easier, despite the loss of peripheral vision.
  • 1440x1080 (4:3): A sharp 4:3 alternative. Provides the exact same stretching benefits as 1280x960 but retains significantly higher pixel density for a less blurry crosshair.
  • 1728x1080 (16:10): The perfect middle ground. Slightly stretched for a minor model width advantage, but retains more peripheral vision and better visual clarity than 4:3.

Frequently Asked Questions

Does stretched resolution give larger hitboxes?

No. The actual in-game hitboxes remain exactly identical in the game engine. However, the visual character model is stretched wider across your physical screen, making it easier for some players to visually track and aim at targets.

Should I change my m_yaw when playing 4:3 stretched?

Most professional players do not change their m_yaw, opting to simply get used to the faster horizontal feeling. Changing m_yaw (e.g., from 0.022 to 0.0165) restores 1:1 horizontal/vertical mouse movement symmetry, but alters your learned muscle memory.

What is the best stretched resolution for CS2?

1280x960 (4:3) is the most popular stretched resolution among CS2 professionals. For players who want a clearer image with less distortion, 1440x1080 (4:3) and 1728x1080 (16:10) are excellent alternatives.
