8.7-Inch Tablet Dimensions in cm and Inches
8.7 inches is Samsung's compact tablet size, used by the Galaxy Tab A7 Lite and Galaxy Tab A9. Here are the exact screen and body measurements, and how the size stacks up against 8-inch and 11-inch tablets.
An 8.7-inch tablet screen measures 19.0 × 11.3 cm (7.47 × 4.46 in), with a 22.1 cm diagonal and 1340 × 800 pixels. The Galaxy Tab A9 body is 211 × 124.7 × 8.0 mm (8.31 × 4.91 × 0.31 in) and weighs 332 g.

8.7-inch tablet screen size in cm and inches
Samsung's 8.7-inch tablets use a 1340 × 800 panel, a 5:3 shape (1.675:1) that is a little longer and narrower than the 16:10 found on most other Android tablets. From that ratio:
Samsung measures the diagonal as if the screen had square corners. The rounded corners take a sliver off the usable area, which is why its spec sheets note that the viewable area is slightly smaller than stated.
The pixel density is about 179 pixels per inch. That is lower than an 8-inch 1280 × 800 screen (189 ppi), because the same number of pixels is stretched over a slightly larger panel.
Galaxy Tab A9 and Tab A7 Lite dimensions
| Model | Inches | Millimeters | Weight | Released |
|---|---|---|---|---|
| Galaxy Tab A9 (SM-X110 Wi-Fi) | 8.31 × 4.91 × 0.31 | 211 × 124.7 × 8.0 | 332 g (11.7 oz) | 2023 |
| Galaxy Tab A7 Lite (SM-T220 Wi-Fi) | 8.37 × 4.91 × 0.31 | 212.5 × 124.7 × 8.0 | 366 g (12.9 oz) | 2021 |
The two share the same screen, width and thickness. The A9 is 1.5 mm shorter and 34 g lighter. Cellular (LTE) versions weigh a few grams more: Samsung lists 371 g for the A7 Lite LTE.
In centimeters, either tablet is about 21.1-21.3 × 12.5 × 0.8 cm. That is almost exactly the height of an A5 sheet (21 cm) but 2.3 cm narrower, so an 8.7-inch tablet slides into most pockets and bags designed for A5 notebooks.
8.7-inch vs 11-inch tablets
Samsung sells the Tab A9 and Tab A9+ side by side, which makes them the cleanest comparison between the two sizes.
| Tab A9 (8.7 in) | Tab A9+ (11 in) | Difference | |
|---|---|---|---|
| Screen (cm) | 19.0 × 11.3 | 23.7 × 14.8 | +4.7 × +3.5 cm |
| Screen area | 215 cm² | 351 cm² | A9+ has 63% more |
| Aspect ratio | 5:3 | 16:10 | A9+ slightly squarer |
| Resolution | 1340 × 800 (179 ppi) | 1920 × 1200 (206 ppi) | A9+ sharper |
| Body (mm) | 211 × 124.7 × 8.0 | 257.1 × 168.7 × 6.9 | +46 × +44 mm |
| Weight | 332 g | 480 g | +148 g |
In practice the 8.7-inch size is a reading, video and kids' tablet that can be held in one hand for an hour. The 11-inch size is better for split-screen apps and for typing on screen in landscape, where the 8.7-inch keyboard is cramped. For the 11-inch class in detail, see the 11-inch tablet dimensions.
8.7 inches compared with 8-inch tablets and the iPad mini
| Screen | Size (cm) | Area | Body (mm) | Weight |
|---|---|---|---|---|
| 8 in 16:10 (Fire HD 8) | 17.2 × 10.8 | 186 cm² | 201.9 × 137.4 | 337 g |
| 8.3 in iPad mini | 17.7 × 11.6 | 204 cm² | 195.4 × 134.8 | 293 g |
| 8.7 in (Tab A9) | 19.0 × 11.3 | 215 cm² | 211 × 124.7 | 332 g |
The 8.7-inch screen is the largest of the three, 16% bigger than an 8-inch 16:10 screen, and its body is the narrowest. That narrow body is easy to grip, but in portrait the screen is only 11.3 cm wide, a little less than the iPad mini's 11.6 cm. The 8-inch tablet page covers the Fire HD 8 and iPad mini in more detail.
Cases, mounts and screen protectors for 8.7-inch tablets
- Screen protectors are cut for the glass of a specific model, not the diagonal. A protector for an 8-inch Fire HD 8 is the wrong shape for a 5:3 Samsung screen.
- Universal 8-inch sleeves sized for 20 × 13-14 cm bodies are too short for the 21.1 cm Galaxy Tab A9. Look for an inside length of at least 21.5 cm.
- Car headrest and bed mounts usually list a clamp range by thickness and width; the 124.7 mm width and 8 mm thickness sit comfortably inside most ranges, but add your case to the measurement.

What are the dimensions of an 8.68-inch tablet?
A screen listed at 8.68 inches with the same 5:3 shape measures about 18.9 × 11.3 cm (7.45 × 4.45 in), effectively the same as 8.7 inches. Manufacturers round the diagonal differently, so cases sold as 8.7-inch usually cover it, but check the body size.
