Duplicating a map copies its layers, styles, popups, extensions, access settings, and other map settings. The copy is independent, so changes to one do not affect the other. Use it to create a version for another audience or scope, or as a template.

## Before you start

- You need permission to delete the map. If you can delete it, you can duplicate it — the portal uses the same rule for both. The map creator or account Owner can do this. See [Account roles reference](/docs/account-roles/account-roles-reference).
- You need to be under your account's map limit. The portal shows the same upgrade dialog you'd see when creating a new map if you've reached it — see [What happens at the map limit](/docs/portals/create-a-map#what-happens-at-the-map-limit).

If you can't duplicate a map, the `…` menu doesn't appear on that map's card at all.

## Open the map card menu

Find the map you want to duplicate. Hover over its card (or its row in list view) and click the `…` button in the top-right corner of the thumbnail.

The menu opens with two items:

- `Duplicate Map`
- `Delete Map`

## Click Duplicate Map

Click `Duplicate Map`. A message shows `Duplicating map...`, then `Map duplicated. Opening copy...`, and the portal opens the new map in the editor.

The copy:

- Carries over every map-level setting — title (with a copy suffix or as `Untitled Map` depending on the map), description, layers, styles, popups, extensions, access settings, custom navigation, layout choices.
- Shares the same underlying datasets — layers reference the same data, so changes to a dataset still flow to both the original and the copy.

## Rename the copy

The copy lands in the editor, ready to edit. Open `Map settings` and change the title to something meaningful before saving — leaving two maps with similar titles makes the portal harder to scan.

See [How to set the map title and description](/docs/map-settings/set-map-title-and-description).
