1000R is a tighter curve than 1500R, and 1500R is tighter than 1800R. The number describes the radius of an imaginary circle in millimetres. It does not tell you the screen’s resolution, refresh rate or overall picture quality.

What do the numbers mean?
| Rating | Imaginary circle radius | Relative curve |
|---|---|---|
| 1000R | 1,000 mm, or 1 metre | The tightest of these three. |
| 1500R | 1,500 mm, or 1.5 metres | A gentler curve than 1000R. |
| 1800R | 1,800 mm, or 1.8 metres | The gentlest of these three. |
The same rule explains a 1900R label: a 1.9-metre radius. A larger R number means a flatter arc. Samsung‘s curvature explanation describes this radius convention. That geometry is useful; claims that one curve is healthiest for everyone are a different matter.
1000R vs 1500R: which should you choose?
Start with the actual screen width and your seat. A strong curve can make the sides of a wide display feel more wrapped around you when you sit near the centre. It can also look unusual if you often lean to one side, share the screen with another person or prefer straight-looking edges for layout work.
- Try 1000R if you want a pronounced wraparound feel and can sit centrally.
- Try 1500R or 1800R if you prefer a milder curve or want to compare a curved screen with a flat one.
- Try the same size in person where possible. A curve on a small screen does not feel identical to the same R rating on a very wide screen.
Does the R number set your viewing distance?
It gives you a geometric reference, not a rule that everyone must sit exactly one or 1.8 metres away. Choose a distance that lets you read text comfortably and see the whole working area without awkward posture. Adjust the stand, text scaling and room lighting too.
Curvature also does not determine the aspect ratio. Check whether the model is 16:9, 21:9 or another shape instead of assuming that every curved monitor is an ultrawide.
What matters more than the curve?
- Resolution and size: these affect workspace and text sharpness.
- Refresh rate and response behaviour: these affect motion. Our FPS and human vision guide explains why these are separate from curvature.
- Ports: match your computer and the resolution/refresh rate you want. Older connections are covered in our DVI guide.
- Stand and mounting: check dimensions, adjustment and the specified VESA mount.
One curved monitor or two screens?
Compare usable workspace, desk depth and the programs you run. A large curved display is not automatically a better replacement for two monitors. Our dual-monitor setup guide covers the other option. Avoid choosing by the R number alone or expecting a curve to fix poor resolution, reflections or unsuitable seating.
Frequently asked questions
Which curve is strongest: 1000R, 1500R or 1800R?
1000R is the tightest of those three. A lower radius number means a stronger curve.
Does 1500R mean a 1,500 mm-wide monitor?
No. It describes an imaginary circle’s radius, not screen width.
Must I sit exactly one metre from a 1000R screen?
No. Choose a comfortable distance for the actual screen size, text and workspace.
Is 1000R automatically best for gaming?
No. Also compare resolution, motion performance, ports, size and your seating position.
