How the calculation works
In OBS, every source has a Source Transform — position (X, Y) and size (Width, Height) in pixels relative to your canvas. This calculator computes those values based on your canvas dimensions and the corner you choose.
A 20 px padding is applied from each edge to keep the facecam from sitting flush against the border. To apply the values in OBS, right-click your webcam source → Transform → Edit Transform and enter the Position and Size values shown below.
For a circular facecam, apply a Mask/Blend filter to your webcam source in OBS (Filter → Add → Mask/Blend, select a circular PNG mask). The position and size values remain the same.
Frequently asked questions
Where do I enter these values in OBS?
Right-click your webcam source in the Sources list → Transform → Edit Transform. Enter the Position X/Y and Size Width/Height shown by this calculator. Make sure 'Use canvas coordinates' is checked.
Which corner is best for gaming?
Top-right is the safest default for most games — the majority of in-game UIs (health bars, minimaps) avoid that corner. Bottom-left is a good alternative. Avoid bottom-right for games with minimaps (MOBAs, open-world RPGs).
What facecam size should I use?
For gaming, Small (320×180) or Medium (480×270) keeps the game visible. Just Chatting streams typically use Large (640×360) or larger — viewers are there to watch you, not a game.
Does this work for 1440p or 4K canvases?
Yes — select your canvas size from the dropdown and the calculator scales all values accordingly. The output bitrate in OBS is separate from canvas size.
How do I make my facecam a circle in OBS?
Add a Mask/Blend filter to your webcam source, set the type to 'Image' and use a white circle on a black background PNG as the mask. You can find free circular masks by searching 'OBS circle webcam mask PNG'.
