Screen sizes and breakpoints

Windows apps can run on any device running Windows, which includes phones, tablets, desktops, TVs, and more. With a huge number of device targets and screen sizes across the WindowsВ 10 ecosystem, rather than optimizing your UI for each device, we recommended designing for a few key width categories (also called «breakpoints»):

• Small (smaller than 640px)
• Medium (641px to 1007px)
• Large (1008px and larger)

When designing for specific breakpoints, design for the amount of screen space available to your app (the app’s window), not the screen size. When the app is running full-screen, the app window is the same size as the screen, but when the app is not full-screen, the window is smaller than the screen.

Breakpoints

This table describes the different size classes and breakpoints.

Size class	Breakpoints	Typical screen size (diagonal)	Devices	Window sizes
Small	640px or less	4″ to 6″; 20″ to 65″	Phones, TVs	320×569, 360×640, 480×854
Medium	641px to 1007px	7″ to 12″	Phablets, tablets	960×540
Large	1008px or greater	13″ and larger	PCs, laptops, Surface Hubs	1024×640, 1366×768, 1920×1080

Why are TVs considered «small»?

While most TVs are physically quite large (40 to 65 inches is common) and have high resolutions (HD or 4k), designing for a 1080P TV that you view from 10 feet away is different from designing for a 1080p monitor sitting a foot away on your desk. When you account for distance, the TV’s 1080 pixels are more like a 540-pixel monitor that’s much closer.

UWP’s effective pixel system automatically takes viewing distance in account for you. When you specify a size for a control or a breakpoint range, you’re actually using «effective» pixels. For example, if you create responsive code for 1080 pixels and higher, a 1080 monitor will use that code, but a 1080p TV will not—because although a 1080p TV has 1080 physical pixels, it only has 540 effective pixels. Which makes designing for a TV similar to designing for a phone.

Effective pixels and scale factor

UWP apps automatically scale your UI to guarantee that your app will be legible on all Windows 10 devices. Windows automatically scales for each display based on its DPI (dots-per-inch) and the viewing distance of the device. Users can override the default value and by going to Settings > Display > Scale and layout settings page.

Change the size of a picture, shape, text box, or WordArt

You can easily resize pictures, text boxes, shapes, and WordArt in your Office file. You can also remove unwanted portions of a picture by cropping it.

If you want to stretch, shrink, or just change the size of a picture (or shape), use the sizing handles or for more precise control, the Size options on the Picture Tools Format tab or the Drawing Tools Format tab.

Microsoft 365 subscribers who have a touch screen may use a finger or a digital stylus to grab a sizing handle.

Click the dropdown control below for more details.

Click the picture, shape, WordArt, or other object (such as a chart) that you want to resize.

To increase or decrease the size in one or more directions, drag a sizing handle away from or toward the center, while doing one of the following:

To keep the center in the same place, press and hold Ctrl while you drag the sizing handle.

To maintain the proportions, press and hold Shift while you drag the sizing handle.

To both maintain the proportions and keep the center in the same place, press and hold both Ctrl and Shift while you drag the sizing handle.

Note: Resizing a WordArt object in this way only resizes the box the WordArt is in. The actual WordArt text behaves just like any other text. If you want to resize it simply select the text you want to resize and change the font size on the Home tab of the ribbon.

Click to select the picture, shape, WordArt, or other object that you want to precisely resize.

To resize multiple objects at the same time, press and hold Ctrl while selecting each object.

Depending on the type of object you’ve selected, do one of the following:

To resize a picture, on the Picture Tools Format tab, in the Size group, enter the new measurements into the Height and Width boxes.

To resize a shape or other object, on the Drawing Tools Format tab, in the Size group, enter the measurements you want into the Height and Width boxes.

Note: If your screen size is smaller, you might need to click the down arrow in the Size group to see the Height and Width boxes.

If you’re not able to change the height and width independently, you’ll need to unlock the aspect ratio:

Click the dialog box launcher in the bottom right corner of the Size group.

In the format pane or dialog box that appears, clear the Lock aspect ratio check box.

Click the picture, shape, WordArt, or other object that you want to resize.

Do one of the following:

To resize a picture, on the Picture Tools Format tab, in the Size group, click the dialog box launcher .

To resize a shape or other object, on the Drawing Tools Format tab, in the Size group, click the dialog box launcher .

If your screen size is smaller, you might need to click the down arrow in the Size group to see the dialog box launcher.

In the format pane or dialog box that appears, do one of the following:

To maintain the original proportion, select the Lock aspect ration check box and enter a Scale percentage for Height or Width.

To resize to a different proportion, clear the Lock aspect ratio check box and enter Scale percentages for Height and Width.
