11 x 17" Ultra-PRO® Toploader.
11-1/4 x 17-1/4" (inside).
16 gauge rigid vinyl.

These work really well for displaying my Photography while maintaining the level of protection I need to keep the print protected as people thumb through them. Other reviews say they aren't crystal clear but they are pretty darn close. My measurements indicate very minimal cool color shift of only +550K I found my RGB values at R:89.1 G:89.2 B:89.3 vs R:94.1 G:94.2 B:93.5 when measuring a white piece of paper inside and outside the toploader. It's simply the nature of the plastic.

It was not as rigid as I interpreted from the description. Nonetheless it served my purpose well and it is a great product. I may buy more of these again if I need to.

I was already familiar with these when I bought them and for my purposes they are fine. But as other people point out, they are advertised as being "ultra clear" by the manufacturer Ultra Pro and Bags Unlimited copies that on their website, which is a mistake to do. The top loaders are made with a plastic that has a blue tint to it, which tends to make whatever you slide into it quite dull. So keep that in mind. Keeping in mind that I already was familiar with them and they served my purposes, I'm rating the product that way. But to be clear, I do believe Ultra Pro should find a way to make them so they're actually clear without the blue tint.

I use these for my collection of comic book original art and am fully satisfied. Add the Toploader Closure Clips and it's a great way to preserve and display original art and small posters. The ones I received were perfectly clear and adequately rigid, although a bit flexible as you might imagine a big sheet of thin plastic would be.

Perfect for our poster sales. We sell more posters with toploaders.

Just right for my purpose of holding an 17 x 11 horizontal message insert on an indoor sign. We added double sided adhesive to the back perimeter for holding the sleeve in place on a coroplast panel.

Perfect! Just the thing for small posters.

Love these poster sleeves, great for small posters to keep them neat on the wall.

These are a bit flimsier than others I've worked with and also a smidge larger - my normal supplier was out of this particular product and I needed it right away. Overall these cost me a bit more for a slightly over-sized and flimsier product - would order again if I absolutely had to, otherwise would avoid. Thank you.

The description says "crystal-clear rigid vinyl." They are indeed built of decent sturdy plastic (though they do generate a little too much static electricity to put in flimsy paper easily), but calling them "crystal-clear" is an outright lie. They're very lavender.
