Monitor size comparison, drawn to scale.
A screen size comparison drawn to scale: put any monitors side by side on your actual desk — 24″ vs 27″, a 34″ ultrawide vs a 32″, or two 27s vs a 49″ super ultrawide — and see real widths, heights and screen area.

Every thumbnail is drawn to the same scale as the real screens.
24" vs 27"
A 27-inch screen has about 27% more area than a 24-inch and is roughly 2.6 inches wider. It is the most common upgrade: pair 27 inches with 1440p for sharp text, while 24 inches at 1080p remains the budget and esports pick.
27" vs 32"
A 32-inch monitor gives about 40% more screen area and is 4.4 inches wider than a 27-inch. Choose 32 inches if you are going 4K and sit at least 28 inches back; stay with 27 inches at 1440p for a shallow desk or fast competitive games.
24" vs 27" vs 32"
The three most popular monitor sizes. A 27-inch has about 27% more area than a 24-inch, and a 32-inch has about 40% more than a 27-inch. For most people, 27 inches at 1440p is the sweet spot.
27" vs 34" Ultrawide
A 34-inch ultrawide is about the same height as a 27-inch 16:9 screen but roughly 7.7 inches wider, for about a third more area. It is the classic upgrade if you want more horizontal space without a taller screen.
34" Ultrawide vs Dual 27"
Two 27-inch monitors give about 49% more screen area and are much wider (about 47 inches vs 31), with a bezel down the middle. The 34-inch ultrawide is the cleaner, more immersive single screen and fits smaller desks.
32" vs 34" Ultrawide
These have nearly the same screen area. The ultrawide trades about 2.3 inches of height for 3.3 inches of width: better for side-by-side windows and immersive games, while the 32-inch is better for tall documents and 16:9 video.
49" Super Ultrawide vs Dual 27"
Practically identical screen area and height: a 49-inch 32:9 monitor is two 27-inch 1440p screens joined without a bezel. Dual 27s cost less and can be angled independently; the 49 gives one seamless canvas.
Triple 24"
Three 24-inch monitors span about 63 inches of screen width before bezels, so you need a desk at least 5.5 feet wide — or angle the side screens inward.

Monitor setup visualizer
Arrange dual, stacked, triple or vertical screens on stands or a monitor arm, check the arm's reach, and set every screen at eye level.
Dual monitor setup planner
Plan a dual monitor setup to scale: how wide two 24″, 27″ or 32″ monitors are, the desk you need, dual monitor arm reach, and how high to set them.
Stacked monitor setup planner
Stack monitors or put them side by side? See a stacked setup to scale, how high the top screen ends up, and the pole height a stacked monitor arm needs.
Triple monitor setup planner
Plan a triple monitor setup to scale: how wide three 24″ or 27″ screens are flat and angled, how they compare with a 49″ super ultrawide, and how to mount them.
Vertical monitor setup planner
Plan a vertical (portrait) monitor setup for coding or reading: how tall a 24″ or 27″ monitor is turned vertical, where to put it and how high to mount it.

A monitor's size is its diagonal, so a 27″ screen isn't 27″ wide. Here are the real widths and heights.
04Questions
Monitor size, answered
More detail in the monitor size guide.
How is monitor size measured?
Monitor size is the diagonal of the visible screen, corner to corner. The actual width and height depend on the aspect ratio: a 27-inch 16:9 monitor is about 23.5″ wide and 13.2″ tall, while a 34-inch 21:9 ultrawide is about 31.2″ wide but only 13.4″ tall.
How much bigger is a 27-inch monitor than a 24-inch?
A 27-inch 16:9 monitor has about 27% more screen area than a 24-inch. It is roughly 2.6″ wider and 1.5″ taller.
Is a 34-inch ultrawide bigger than a 32-inch monitor?
They have almost the same screen area. The 34-inch ultrawide is about 3.3″ wider but 2.3″ shorter, so it is better for side-by-side windows and immersive games, while the 32-inch is better for tall documents and 16:9 video.
Is a 49-inch super ultrawide the same as two 27-inch monitors?
Nearly. A 49-inch 32:9 monitor has practically the same width, height and screen area as two 27-inch 16:9 monitors side by side, without the bezel in the middle.
