We often find ourselves in situations where we need to measure something, but don’t have a ruler handy. It is a convenient and accurate on-screen online ruler for any device, be it a desktop, laptop or mobile phone. In other words, although the iPhone X's diagonal is 6.3% longer, its area is only 0.5% bigger (iPhone X also has a big cutout and curved edges, but we are not taking them into account - even with that simplification, the screen area is still very similar). Ruler Online is an online ruler that can be used to measure in mm, cm and inches. So even though the first iPhone has a longer diagonal, the screen size is almost the same as iPhone 8 plus'. And what do you get? 4.8" for screen width, 2.7" height, and 12.93 in² screen size. Repeat the steps for iPhone 8 Plus, choosing a 16:9 aspect ratio and 5.5-inch diagonal. In our case, those are equal to 5.3", 2.45", and 13 in². Now, one thing to keep in mind is that the actual size of a 7-inch tablet includes the bezels, so if the bezels are very thick, the screen will actually be between 6.8 and 6.5 inches.
As a result, you obtain screen dimensions: width and height and the screen area.The first value of the aspect ratio is 2.17, and the second value is 1. As that ratio is still not very popular, you can't select it from a drop-down menu - write it down manually in advanced options fields. Let's start with iPhone X with an aspect ratio equal to 2.17:1. For instance, a 6' CMU is nominally 6' deep while a 10' CMU is nominally 10' deep. To get accurate Ruler, print on US Letter paper size (8.5 × 11 inches). Ensure you are printing at 100 or actual size to guarantee accuracy. PDF format for easy download and printing. We could expect that the former would have a bigger screen, but we can't forget about aspect ratios! iPhone X has a narrower screen with a 2.17:1 ratio, and iPhone 8 Plus has a standard 16:9. Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. Inches and centimeters are available in this easy to use 12-inch ruler with 1/16-inch markings.
Let's say we want to compare two smartphones: The Apple iPhone X with a 5.85-inch display, and the iPhone 8 Plus, which has a 5.5-inch screen.
