This large linen bound photo album is very generously sized at approx 31cms by 32cms by 4.5cms. It fits four (six at a squeeze!) 6" x 4" photos per side of page, see photos, and with 40 pages, that's 80 sides so you can fit 400 comfortably, 480 at the max!
You need double sided tape, photo corners, glue dots or photo mounting squares (we sell the latter) if you want to fix photos in to the book.
We also sell a presentation box for preserving and protecting your wedding guest book for the future.
