16:10 Aspect Ratio Calculator
Enter a width or height to scale any image, video, or screen to the 16:10 aspect ratio. Optionally add a physical diagonal size to get pixel density (PPI) and display area. The result panel shows the math step by step, a reference table of common 16:10 resolutions, and how the ratio compares to 16:9.
What is the 16:10 aspect ratio?
The 16:10 aspect ratio (also written as 8:5) means that for every 16 units of width, there are exactly 10 units of height, giving a ratio of 1.6:1. This places it between the square 4:3 format and the widescreen 16:9 format. It was the dominant widescreen standard for laptop screens and professional monitors throughout the early 2000s before 16:9 took over the consumer market. Today 16:10 has made a strong comeback in premium productivity laptops, drawing tablets, and e-ink readers because the extra vertical space relative to 16:9 reduces scrolling and shows more of a document, spreadsheet, or code editor at once.
How to calculate 16:10 dimensions
The core formula is simple. To find the height from a known width, multiply the width by 10 and divide by 16 (height = width x 10/16). To find the width from a known height, multiply the height by 16 and divide by 10 (width = height x 16/10). For example, a 1920 px wide image must be 1920 x 10/16 = 1200 px tall to match 16:10. The physical diagonal of a screen can be found with the Pythagorean theorem: diagonal = sqrt(width^2 + height^2) in pixels. Dividing that pixel diagonal by the physical diagonal in inches gives the pixel density in pixels per inch (PPI).
16:10 vs 16:9: which is better for productivity?
At the same width, a 16:10 display is about 11% taller than a 16:9 display (1200 px vs 1080 px at 1920 px wide, adding 120 rows). That difference matters for code editors, where you see more lines without scrolling; for PDF and word-processing documents, where A4 and US Letter paper are naturally taller than 16:9; and for photo and video editing timelines, where the extra vertical space accommodates tool panels without shrinking the canvas. For watching HD video content, 16:9 is the native format, so 16:10 displays will show thin letterbox bars when playing back 1920x1080 material full-screen. Most professionals today prefer 16:10 for desk work and accept the minor letterboxing for occasional video.
Pixel density (PPI) and display sharpness
Pixel density measures how tightly pixels are packed per linear inch of screen surface. It is calculated as the pixel diagonal divided by the physical diagonal in inches. On a 24-inch 1920x1200 monitor the pixel diagonal is sqrt(1920^2 + 1200^2) = about 2263 px, giving 2263 / 24 = 94 PPI, which is comfortable for a desk display viewed from around 60 cm. A 13-inch 2560x1600 laptop panel gives about 228 PPI, which Apple classifies as Retina: individual pixels become indistinguishable at normal viewing distance. For desktop monitors the sweet spot is roughly 90 to 140 PPI; for phones and tablets above 220 PPI is preferred; and for large TV panels 40 to 80 PPI is normal because viewing distance is greater.

Frequently asked questions
What is the 16:10 aspect ratio in decimal?
16 divided by 10 equals 1.6, so the 16:10 aspect ratio is exactly 1.6:1. You can verify any image or screen by dividing its width by its height: a result of 1.6 (or very close to it) confirms the 16:10 ratio. The ratio is also written as 8:5 in its lowest terms, which is 16 and 10 both divided by their greatest common factor of 2.
How does 16:10 compare to 16:9?
Both ratios share the same width unit (16), but 16:10 is taller (10 height units vs 9). At 1920 px wide, 16:10 gives 1200 px of height while 16:9 gives 1080 px, a difference of 120 rows, or about 11% more vertical space. The extra height is useful for documents, spreadsheets, code editors, and design tools. The trade-off is that standard HD video (1920x1080, 1280x720) is in 16:9, so playback on a 16:10 screen adds thin black bars at the top and bottom.
Which devices use 16:10 screens?
Many premium productivity laptops including recent MacBook Pro and MacBook Air models, Lenovo ThinkPad X1 Carbon, Dell XPS series, and various drawing tablets use 16:10 panels. Professional desktop monitors from Dell UltraSharp, ASUS ProArt, and BenQ series offer 16:10 as an alternative to 16:9. E-ink readers and tablets with stylus input also favor 16:10 or the even taller 3:2 ratio because they are designed for reading and writing rather than video.
How do I resize an image to 16:10 without cropping?
If you want to add letterbox (horizontal black bars) or pillarbox (vertical bars) instead of cropping, calculate the 16:10 canvas size for your target width, then center the original image on that canvas. Most image editors (Photoshop, GIMP, Affinity Photo) have a canvas-resize or fit-to-canvas mode. If you prefer to crop, find the largest 16:10 rectangle that fits inside your source image, centered on the subject, then export at that crop.
What is PPI and how is it calculated for a 16:10 screen?
PPI stands for pixels per inch and measures display sharpness. To calculate it: first find the pixel diagonal using the Pythagorean theorem (diagonal_px = sqrt(width_px^2 + height_px^2)), then divide by the physical screen diagonal in inches. For a 24-inch 1920x1200 screen the pixel diagonal is about 2263 px, giving 2263 / 24 = approximately 94 PPI. The higher the PPI, the sharper the image, especially when viewed close up.
Is 16:10 the same as 8:5?
Yes, 16:10 and 8:5 are exactly the same ratio. Both 16 and 10 divide evenly by 2, giving the reduced form 8:5. Manufacturers and display specifications sometimes use one name and sometimes the other, but they describe an identical width-to-height proportion of 1.6.
