Memories provides unlimited space on all Timelines. So you can add as many Memories and media (photos and videos) to your Timeline as you like.
On the app, each Memory is limited to a maximum of 10 photos* (regardless of the storage plan). To add more than 10 photos to a single Memory, create another Memory. Of course, you can add unlimited Memories to your Timeline.
*The limit of 10 photos is only on the app, you can use our web platform if you are adding more than 10 photos.
