Love the quality of these page protectors. Slighty larger than 6 x 8.More like 6 1/4 x 8. So just be cautious when croping pages. If you cut them to true 6 x 8 they tend to slip out easily.
I bought these to make a simple photo album with 6x8 pictures, and the sheet protectors ARE a little bit bigger than 6x8 so the photos are just the tiniest bit loose inside them. Maybe 1/8 of an inch side to side. This would be helpful if you were making layouts with thicker embellishments, but for this use I do wish they were exactly 6x8. They seem sturdy and well made.
The 6 x 8 page protectors and the multi pack are AWESOME! I love using them in my albums to protect my photos, my journaling and to create adorable shaker pages. You can create a full 6 x 8 shaker page or use any of the sections in the multi pack pages to create a shaker pocket-such a cute embellishment in your album.
