Curved Monitor Visualizer
Visualize and compare different monitor curvatures and their depth.
Screen A
Note: 21:9 screens are often not exactly 21:9, but very close.
How to use this tool
Enter the diagonal size
Type the curved monitor's diagonal in inches (or centimeters with the unit toggle). For a 34-inch ultrawide, enter 34. The diagonal defines how wide the panel is before any curvature is applied.
Set the aspect ratio
Pick 16:9, 21:9, 32:9, or any custom width:height pair. Ultrawides are almost always 21:9 and super ultrawides 32:9, so the preset matches most curved monitors on the market.
Choose the curve rating
Enter the R rating in millimeters (800R, 1000R, 1500R, 1800R, or 0 for flat). Smaller R means more aggressive curve. The visualizer renders the top-down footprint of the panel at that curve.
Compare against a flat reference
Add a second display with a different curve rating (or 0 for flat) to overlay both top-down views. See exactly how much desk depth the curve consumes and where the ideal viewing distance sits.
About this tool
The Curved Monitor Visualizer renders an accurate top-down view of curved displays so you can see what 800R, 1000R, 1500R, and 1800R actually look like before you spend hundreds on a panel you've never tried. Curve specs are quoted as a radius in millimeters, smaller is more curved, but that number is abstract until you visualize it alongside other options or a flat reference.
Use it when you're choosing between curved and flat monitors, comparing different curve ratings across brands, or checking whether an aggressive curve matches your desk setup. Enter the diagonal size, aspect ratio, and curvature rating for any display; the visualizer draws the physical footprint of the panel and overlays the correct viewing distance so you can decide if your chair is at the sweet spot.
Formula
A monitor with an R rating of N mm has a curve radius of N millimeters. The arc length of a curved panel is the flat width of the same display, so the physical depth added by the curve is R - sqrt(R² - (width/2)²). The ideal viewing distance equals R. Sitting at that distance, every part of the screen is equidistant from your eye.
When to use it
Reach for this tool when deciding between a curved ultrawide and a flat widescreen, or comparing two monitors that have similar specs but different curves (e.g. a 1000R 34-inch vs. a 1500R 34-inch), or checking whether your desk has enough depth to sit at the ideal distance for the curve. Pair with the Screen Size Comparison to see how much more desk space the physical curve will consume.
