# Resize and collapse inbox panels

> Shape the five-column inbox to your screen, with the mouse or the keyboard.

The inbox has five columns: the app rail, the views sidebar, the conversation list, the thread and the details panel. You can adjust most of them.

## Resize

Drag the edge between two panels. The thread takes the remaining space and never gets narrower than 320 pixels.

| Panel | Narrowest | Widest | Default |
|---|---|---|---|
| Views | 180 | 320 | 220 |
| Conversation list | 260 | 480 | 320 |
| Details | 260 | 440 | 300 |

## Use the keyboard

Focus an edge with Tab. Press the left or right arrow to move it 16 pixels at a time. Double-click an edge to reset it to the default.

## Collapse

The list icon in the thread header hides the views sidebar. The panel icon hides the details panel. Both buttons report whether they are expanded to screen readers.

## Small screens

Below 960 pixels wide only the conversation list shows. Opening a conversation takes you to the thread at full width, with a back button to return to the list.
