Curved Monitor Calculator
Find the ideal curve radius for your screen size and viewing distance
Enter Screen Size
Input your monitor’s diagonal size. Curved monitors are most beneficial for sizes 32 inches and above, especially ultrawide formats.
Select Curve Radius
1000R means the curve has a radius of 1000mm. Lower numbers = more aggressive curve. 1500R is most common for ultrawides.
Set Viewing Distance
Measure your typical sitting distance from the screen. Ideally, the curve radius should match your viewing distance for uniform focus distance across the screen.
Why Curve Matters
Curved screens wrap around your field of view, keeping all parts of the screen equidistant from your eyes, reducing eye strain on wide displays.
Ideal Curve Matching
The ideal curve radius equals your viewing distance. Sitting at 70cm? A 700R curve would be perfect, but 1000R-1500R is usually fine.
Curve vs Size
Larger screens benefit more from curvature. A curve on a 27" 16:9 is unnecessary, but essential for 49" 32:9 super ultrawides.
Gaming vs Productivity
Gaming benefits from immersive curves (1000R-1500R). For productivity and design work, flatter curves (1800R+) reduce distortion.
Frequently Asked Questions
What does 1800R or 1500R mean on a curved monitor?
The number before ‘R’ is the radius of the curvature circle in millimeters. A 1800R monitor curves along an arc with a 1800mm (180 cm) radius; a 1500R monitor curves more tightly with a 1500mm radius. The smaller the R value, the more aggressive the curve. The recommended viewing distance approximately equals the radius: sit 1.8 m from a 1800R panel and 1.5 m from a 1500R panel for optimal edge-to-center equidistance.
Does a curved monitor reduce eye strain compared to a flat panel?
For single-seat close-distance use, a curve matched to the viewing distance keeps all screen points at approximately the same focal distance, potentially reducing constant focal adjustment across a wide field of view. Evidence from ergonomics studies is mixed, but users of 32-inch and wider ultrawides (34-49 inches) consistently report reduced strain with curvature. Flat panels remain preferred in multi-viewer environments where the curve benefits only the center seat.
Is a 1000R curve too aggressive for a desktop monitor?
1000R (1-meter radius) is the most extreme curvature currently marketed, typically found on 49-inch super-ultrawides. At a standard 60-70 cm desk distance, a 1000R curve is more pronounced than the matching distance suggests — the edges can appear to wrap noticeably toward the viewer. Samsung recommends sitting 1 meter from 1000R panels. For displays under 32 inches, 1800R or 1500R is generally more appropriate.
Does a curved monitor affect image quality compared to flat panels?
Curved panels can introduce slight geometric distortion when displaying straight vertical lines near the screen edges, visible on strict test patterns. For photography and graphic design where geometric accuracy matters, flat panels are preferred. For gaming and productivity, the distortion is rarely perceptible. Color uniformity can also vary slightly from center to edges on curved panels due to changing light incidence angles on LCD backlights.
What is the field of view angle at a given curved monitor size and viewing distance?
The calculator derives the arc angle (in degrees) from the screen width and radius: angle = 2 × arcsin(width / (2 × radius)). A 34-inch 21:9 monitor is roughly 800 mm wide; at 1800R, the arc subtends about 25 degrees. Viewed at 600 mm, the horizontal field of view is approximately 68 degrees. The THX recommendation for cinematic immersion is a 40-degree viewing angle, suggesting that users can sit closer to large curved ultrawides than traditional ergonomic guidelines suggest.
