How do I test my website on different screen sizes?
Quick checks you can do
Most builders include a preview mode for phones and tablets. Use it to see how each page reflows when the screen gets narrower. Look for text that is too small, images that stretch and menus that are hard to open.
Browsers also let you resize the window to see how the layout shifts. Narrow the window slowly and watch for overlapping elements or horizontal scrolling.
- Use the builder's mobile preview
- Test on a real phone
- Resize the browser window slowly
- Look for horizontal scrolling
Testing with real people
Ask a friend to open the site on their own device and try a simple task, such as finding your contact page. Watching them can reveal problems you would miss, such as a button that looks clickable but is not.
Repeat these checks after each major change. Small updates can shift layouts in ways you do not expect, so a short routine keeps the site looking right. Test the site once a month as well, since updates to the theme or browser can change how pages look. Keep notes about any layout issue you find so it is easy to fix. Fix the most visible problems first, such as broken menus or hard-to-read text.
Common mistakes
- Testing only on a large monitor and assuming phones look the same.
- Skipping checks after a theme or template update.
