How to review and adjust the mobile and tablet version of a page
In the builder, use the device switcher (desktop, tablet, mobile) to view and edit each version, and enter a pixel width in Device Width to test other screen sizes. Changes made in mobile mode (e.g. an image size) apply to mobile only.

Before you start
- Have the page created in a funnel or website and open in the builder.
- Build the desktop version first. Tablet and mobile inherit from it until you customize them.
- Keep a phone handy to check at the end: the preview helps, but the real test is on the device.
Where to find it
Sites › Funnels or Websites › (open the page) › Edit › device switcher (Desktop / Tablet / Mobile)
Step by step
View the page on each device
- Open Sites, choose Funnels or Websites and click Edit on the page.
- In the builder bar, click the device switcher and choose Desktop, Tablet or Mobile. The selected mode sets which version you're viewing and editing.
- To test a specific size, type a pixel width into the Device Width field next to the switcher. Each mode accepts a range: desktop 1025 to 3000 px, tablet 768 to 1024 px, mobile 320 to 767 px.
- Click Apply or press Enter. The canvas changes to that width; if it's wider than your screen, scroll horizontally.
- Review sections, rows, columns, text and spacing at that width. Repeat with other widths or another mode.
- Use the reset option to return to the mode's default width.
Resize an image for mobile only
- Switch to Mobile mode.
- Click the image to open its settings.
- Under Height and Width, enter the values and choose the unit:
px(fixed),%(relative to available space) orrem/em(relative to text size). You can mix units, for example height in px and width in %. - Save. These values apply to mobile only; the desktop version keeps its own.
- Click Preview and check both modes.
Adjust rows and columns on tablet
- Switch to Tablet mode.
- Select the row and adjust its Width.
- To redistribute adjacent columns, drag the handle between them.
- Switch back to Desktop to confirm nothing changed there, then save.
Tips
- The width you type into Device Width is preview only: it doesn't create a new breakpoint, isn't saved and doesn't change the published page. Reloading the builder resets it.
- On mobile, rows always span the full width and columns stack on top of each other; the row width control is hidden.
- Tablet inherits desktop widths. To restore inheritance after customizing, set the tablet row width to the same value as desktop.
- If you don't set mobile dimensions, the image uses the desktop ones, which are usually too large for small screens.
Common problems
- The width field rejects my value → It's outside the range for the selected mode. Switch modes (e.g. to tablet) or enter a value within the range.
- I resized on mobile and desktop changed too → Make sure the switcher was on Mobile before editing. Changes apply to whichever mode is selected.
- The image is still huge on mobile → It has no mobile-specific dimensions yet. In Mobile mode, set the width in
%(e.g. 100%) so it follows the screen. - Columns are too narrow on tablet → In Tablet mode, drag the handle between columns or adjust the row width. This doesn't affect the desktop version.
- It looks different on a real phone than in the preview → Publish the page and open the address on your phone; if you used several widths on the same page, check each section in Mobile mode.
