The maximum number of photos a book can hold depends on the book's size. Although each size has a maximum of 300 pages, you can fit a lot more than in a 12x10 than an 8x8! Image limits are as follows:
8x8 = up to 150
11x8 = up to 250
12x10 = up to 300
Most projects don't come close to reaching the max, but you'll want to keep this in mind if you're making a photo-heavy book. If your project has more than 400 images, you'll want to consider removing some of them or splitting the book into two volumes. You can also speak with our customer success team for custom pricing.
