# Keep a Two-Page Spread Together on Mobile

# Keep a Two-Page Spread Together on Mobile

By default, Simplebooklet displays pages individually on mobile for easier reading on smaller screens. If your booklet has a two-page spread that needs to stay together — like a full-width image or a layout that spans both pages — you can change your mobile **Page Flip Transition** to keep the spread intact.

The **Mobile** setting controls how your Simplebooklet appears on both phones and tablets — there's no separate tablet setting to configure.

## How to Change the Mobile Page Flip Transition

1. From your **Dashboard**, click the **Design** tab for the Simplebooklet you want to update.

> The **Mobile** settings apply to both mobile phones and tablets.

## Preview Your Changes

Open **Preview Mode** and switch to the mobile preview to confirm your spread is displaying correctly before you share it. This gives you a true picture of the reader experience on smaller screens.
