How to Change Display Size on Your Device

Understanding Display Size and Why It Matters

Display size refers to the physical dimensions of text, icons, and images shown on your device's screen. This setting controls how large or small content appears, which affects readability and how much information fits on one screen at a time. When you increase display size, everything gets bigger, making it easier to read. When you decrease it, more content fits on the screen, but text and icons become smaller.

Many people adjust their display size for comfort and accessibility. Larger text helps those with vision concerns or eye strain from extended screen use. Smaller display sizes benefit people who want to see more information without scrolling as much. The good news is that most modern devices—whether smartphones, tablets, or computers—allow you to change this setting without special knowledge or tools.

Display size differs from brightness, which controls how bright your screen appears, and resolution, which determines the clarity and sharpness of images. You can adjust all three settings independently. Some devices use the term "scaling" or "zoom" instead of "display size," but they accomplish the same goal of making content larger or smaller.

Understanding where these settings live on your device is the first step toward customizing your viewing experience. Different operating systems place these controls in different locations, which is why learning the specific steps for your device type matters.

Practical takeaway: Before making changes, note your current display size setting. This helps you remember what worked best if you want to return to it later, or helps you explain your preferred setting to someone assisting you.

Changing Display Size on Windows Computers

Windows computers offer several ways to adjust display size, with the most common method being through Display Settings. To begin, right-click on any empty area of your desktop—the background where no icons or windows are open. A menu will appear with various options. Look for "Display settings" and click on it. This opens a window showing your current display configuration and adjustment options.

Once in Display Settings, look for a section labeled "Scale and layout." This area shows your current zoom percentage, typically set to 100% by default. Windows recommends a specific scaling based on your monitor size and resolution, but you can change this to suit your preferences. Click on the dropdown menu under the percentage and select a new size. Common options include 100%, 125%, 150%, and 175%. Selecting a higher number makes everything larger; selecting a lower number makes everything smaller.

After you select a new scaling percentage, Windows may ask you to sign out and sign back in for changes to take full effect. Some changes appear immediately, while others require this restart. If you find the new size uncomfortable after a few hours of use, you can return to Display Settings and choose a different percentage. There is no penalty or limitation for changing this setting multiple times.

For more precise control, some Windows users prefer individual app zoom settings rather than system-wide changes. In Microsoft Word, for example, you can use the zoom slider in the bottom right corner to adjust that specific application's display size without affecting other programs. This approach works well if only certain programs cause eye strain.

Windows also includes a feature called "Magnifier," which works differently from display scaling. Magnifier enlarges a portion of your screen temporarily, useful for examining specific details. You can activate it by pressing the Windows key plus the plus sign (+) key on your keyboard, or by searching "Magnifier" in your Start menu.

Practical takeaway: After changing your display size, spend at least an hour using your computer normally before deciding if the new setting works. What feels too large or too small initially often feels right after your eyes adjust.

Adjusting Display Size on Apple Devices (Mac, iPad, iPhone)

Apple devices provide straightforward methods for adjusting display size across their product line, though the exact steps vary slightly between devices. On a Mac computer, click the Apple menu in the top left corner and select "System Preferences" (or "System Settings" on newer versions). Then click "Displays." This window shows your current resolution and scaling options.

In the Displays window, you'll see options like "Scaled," with several choices available. These choices represent different ways to display content. The "Larger Text" option increases the size of text throughout your system without affecting other interface elements. Simply click on "Larger Text" to see the available sizes. Unlike Windows scaling, Apple's approach sometimes maintains clarity better by adjusting font sizes rather than stretching everything proportionally.

For iPad users, the process differs slightly. Open Settings by tapping the gear icon, then scroll down and tap "Display & Brightness." Look for "Text Size" which adjusts only text throughout the system. For more comprehensive display adjustments, some iPad users prefer "Accessibility" settings, where "Display & Text Size" offers additional zoom options that affect most apps system-wide.

iPhone display size adjustment follows a similar path. Open Settings, tap "Display & Brightness," then "Text Size" to adjust text across the system. For users who need even larger text and icons, iPhone offers "Accessibility" settings. Within Accessibility, you'll find "Display & Text Size" which includes options like "Larger Accessibility Sizes" that significantly increase the size of system elements.

Apple also includes a feature called "Zoom," available in Accessibility settings on all Apple devices. This magnifies a portion of your screen temporarily, much like Windows Magnifier. You can activate it by triple-tapping with two fingers on your screen (iPhone and iPad) or using keyboard shortcuts on Mac. This works within individual apps while keeping the rest of the system at normal size.

Practical takeaway: Apple's "Text Size" slider provides the most consistent experience across Apple devices because it specifically targets readable text rather than all interface elements. Start with this option before exploring more advanced accessibility features.

Modifying Display Size on Android Phones and Tablets

Android devices, used by many manufacturers including Samsung, Google, and others, offer display size adjustments through Settings. Open your device's Settings app—usually represented by a gear icon. Then navigate to "Display" or "Display and brightness." The exact menu names vary by manufacturer and Android version, but these options appear on virtually all Android devices sold in recent years.

Within Display settings, look for "Screen zoom," "Display size," "Font size," or similar options. Android provides more granular control than some other systems, often with separate controls for overall interface size and text size specifically. Move the slider to increase or decrease the size. A slider toward the left makes content smaller; moving it right makes everything larger. Changes usually appear on your screen immediately as you adjust the slider, allowing you to preview the effect before confirming.

Some Android devices also offer "Font size" as a separate setting from overall display scaling. This approach targets only text while leaving icons and buttons at their standard size. If you primarily struggle with reading text, adjusting font size alone might be more effective than changing the entire display zoom, which can sometimes make certain apps appear cramped or awkward.

Google Pixel phones and tablets include an additional feature called "Large text" in Accessibility settings. This provides even larger text options than the standard Font size slider and works across most applications. To access this, go to Settings, then Accessibility, then Display and text size, then turn on "Large text" and choose your preferred size from the available options.

Samsung devices offer "Screen zoom" which works similarly to other Android implementations. On Samsung phones, go to Settings, Display, and Screen zoom. This affects the size of nearly all interface elements system-wide. Samsung also integrates font size options separately if you want to enlarge text without affecting icon sizes.

Practical takeaway: Android's variety of manufacturers means your specific steps might vary from a friend's Android phone. Check your device's manual or manufacturer's website if you cannot locate display size settings in the standard locations.

Using Browser Zoom for Website and App Content

Beyond system-wide display adjustments, most web browsers and applications offer zoom controls for individual use. In web browsers like Chrome, Firefox, Safari, and Edge, you can zoom in on websites without changing your entire device's display settings. This proves useful when one particular website's text feels too small while the rest of your system displays at a comfortable size.
