How are Curved Monitors Measured: The 3 Ways

Table of Contents


How are curved monitors measured? If you’re buying a curved monitor, the first thing you need to do is figure out the dimensions of the curved display. This includes figuring out how much width, height, and depth the monitor has, which will help you determine if it’s going to fit in your workspace, as well as whether it will fit on your desk or mounting arm when you get it home.

To figure this out, though, you need to know the best way to measure a curved monitor so that you don’t waste money on one that doesn’t fit. Fortunately, we’re here to help! There are three main ways to measure your monitor’s curvature: 1800R, 3000R, and 4000R.

1. What are 1800R, 3000R, and 4000R?

1800R is equivalent to an 8-inch radius, 3000R is equal to a 10-inch radius, and 4000R is equal to a 12-inch radius. Generally speaking, anything lower than 1800R will give you that curved feel without taking up too much space.

2. There are 3 main ways to measure your monitor’s curvature

There are three main ways to measure your monitor’s curvature: 1800R, 3000R, and 4000R. The first is a handy formula (d = 0.02r), which allows you to calculate how much distance there is between two parallel lines on your screen. Also, you can use a built-in tool in some monitors to find the radius, but in most cases, you’ll need a ruler and simple arithmetic skills. For starters, measure the size of your monitor to determine its width and height. 

2.1 How to measure 1800R:

The first way is 1800R. It means a 3000mm total curved distance, which means that a straight line from one corner to another will create an arc that measures 1800 millimeters on its outer edge.

2.2 How to measure 3000R:

The second common measurement is the 3000R. The overall curved distance is 3000mm, which uses 30-degree arcs on its outer edge. This means that if you connect opposite corners with a straight line, it will make three full circles as it wraps around your screen.

2.3 How to measure 4000R:

A third way to measure your monitor’s curvature is to use 4000R. The overall curved distance is 4000mm, which again makes use of 3-degree arcs. To measure for 4000R, you need to draw four straight lines that extend from opposite corners of your screen until they meet in a circle at their endpoints.

3. How are Curved Monitors Measured and How do different curvatures affect your viewing experience?

The most common monitor curvatures are 1800R, 3000R, and 4000R. Each one offers a unique range of viewing angles and visual effects. As you may have guessed from their names, a smaller radius means that a monitor is more curved.

Now that you know how different monitor curvatures affect your viewing experience, it’s time to choose a new monitor. Which one should you choose? 1800R has a large range, making it great for most people who don’t have any significant issues with their existing setup. 4000R is an ideal choice for gamers and office workers alike, as it offers additional peripheral vision and visual immersion.

4. Which one is best for me?

There is no one-size-fits-all answer, but you should keep in mind what kind of experience you want out of your curved monitor. For example, if your biggest priority is sheer entertainment value, 4000R is an obvious choice. If instead, you’re looking for productivity and immersion, 3000R monitors might be better suited for you. 1800R monitors seem like they would be ideal, but they are very similar to monitors with a 3000R curve—the difference just isn’t as noticeable or pronounced.

5. What Does the Radius of a Curved Monitor Mean?

A curved monitor’s radius is a measurement of the bend in the screen from one edge to the other. To get a rough estimate of the radius of your screen, take a ruler and place it across your display so that it touches the edges of both sides. The number where the ruler meets will be your monitor’s approximate curvature or radius. The curvier your monitor is, the lower its radius will be.

When it comes to curved monitors, bigger isn’t always better. The curvier your screen is, the wider and heavier it can be. Wider screens usually aren’t practical for workstations as they add more distance between you and your computer, while curved screens are notorious for being heavier because they have a larger radius than flat displays. Don’t fall victim to spending thousands on a monitor with a high radius that you won’t use much or doesn’t fit your desk properly.

6. What Is Horizontal Curvature?

Horizontal curvature refers to when a monitor’s radius is greater than its height, or if you look at it from above, it has a lower radius on its right and left edges than it does in its center. The most common number for horizontal curvature is 1800R, which is what you’ll find on monitors. This means that these monitors have deeper curves along their sides than in their centers. They also have shallower curves along their top and bottom edges compared with their mid-sections. If you choose one 34-inch curved monitor and stand directly in front of it with your eyes level with its center, it will appear flat as an oval shape stretched out into a rectangle.

7. What Is Vertical Curvature?

Vertical curvature (1800R, 3000R, or 4000R) determines how much your monitor curves inwards. The smaller number means a larger curve. Vertical curvature is especially important for dual-monitor setups; if you have a curved monitor and use two monitors side by side, make sure they match up in vertical curvature.

8. Frequently Asked Questions FAQ


8.1 How wide is a 32 inch curved monitor?

A 32-inch curved monitor will be about 2.6 feet wide from edge to edge and 1.8 feet high from the bottom of the screen to the top of the monitor’s curve.

8.2 What is a 34 inch ultrawide monitor equivalent to?

A 34-inch ultrawide monitor would be equivalent to a 40-inch curved monitor. An ultrawide monitor sometimes called an ultra-wide, is typically larger than a traditional widescreen display.

8.3 Is 32 inch monitor ultrawide?

Yes, 32-inch monitors are ultrawide! Ultrawide monitors have a 21:9 aspect ratio, which is wider than the 16:9 widescreen monitor that most people use.


The curvature of monitors is signified with an ‘R’, or radius, which is always measured in millimeters. Every curved monitor will have one of three common measurements: 1800R, 3000R, or 4000R. All you have to remember is that a lower number means a bigger curve. <This part should talk about – The difference between each type: Larger curves (1800R and 3000R) may be more immersive than smaller ones (4000R), but they come at a higher price point as well.
