Calculate perfect aspect ratios, find missing dimensions, and visually compare Native against Stretched resolutions to understand exact FOV and sensitivity impacts.
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.
Instantly calculate a missing resolution width or height based on a target aspect ratio (e.g. 16:9, 21:9).
In CS2 and Valorant, many pro players use stretched resolutions (e.g., forcing 1280x960 4:3 on a 16:9 monitor). This makes character models appear wider on screen, but you lose peripheral FOV and horizontal mouse movement feels faster.
No. Hitboxes remain identical in the game engine. The visual model is stretched wider on your screen, making it easier to track and aim at targets.
Most pros don't — they adapt to the faster horizontal feel. Changing m_yaw (e.g., 0.022 to 0.0165) restores 1:1 mouse movement but alters your muscle memory.
1280x960 (4:3) is the most popular. For a clearer image, try 1440x1080 (4:3) or 1728x1080 (16:10).
16:9 is the standard for competitive gaming. Ultrawide 21:9 provides more peripheral vision but may not be supported in all competitive titles.
Divide your resolution width by height and simplify. For example, 1920/1080 = 16/9. This calculator does it automatically.
Content appears stretched or squished, and black bars may appear on the sides or top/bottom of the screen.
