Your theme is the design your visitors see — the colours, the type, the layout. WordPress lets you try a different one on before you commit, so nothing changes for your visitors until you say so.

## Before you start

- An administrator account, or another role that's allowed to manage themes.
- Any extra themes you want to try already installed on your site.

## Steps

### Step 1: Open the theme's details

In the dashboard, find **Appearance** in the left-hand menu and click it, then click **Themes**. Hover over the theme you're curious about and click **Theme Details** on its card.

### Step 2: Preview it, then make it yours

Click **Live Preview** to walk through your own site wearing the new theme — your visitors still see the old one. When you're happy, click **Activate** to switch your site over. To remove a theme you're finished with instead, click **Delete**.

## A few things worth knowing

- Your content comes with you. Posts, pages, menus, and media all stay exactly where they are when you switch.
- You can't delete the theme you're currently using. Switch to another one first, then come back and remove it.
- Changed your mind? The old theme is still installed, so you can switch straight back to it.

## Summary

Try any installed theme on your live site before you commit, switch to it when you're happy, and tidy up by deleting the ones you're done with — all from **Appearance** → **Themes**.
