Standard sizes
Over the years, poster frames have gone through a lot of development on the basis of the size of concert posters, movie posters, and format art prints.
Construction
The border is made of plastic and a plexiglass that covers the poster. The back is made from cardboard, which makes the frame lightweight. For easy hanging, the back has a hook as well.
There is an option to install a mat as well. However, you won’t see double matting in these frames because they will add extra weight.
Snap Frames
Snap frames is another great option. Usually, snap frames load the photos from the very front, which allows you to replace the photo without removing the frame. For ease of access, all of the sides of the frame are open. They are good for movie posters.
Acid-free poster frames
When buying a poster frame, make sure you know whether it’s acid-free or archival. Ask yourself if you need to use a poster to beautify your room or you need to use one to preserve a memorabilia or a piece of art. If you want to use it for preservation purposes, you should give a go to a higher quality material.
Archival Poster Frames
If you want to preserve an artifact, you can take your poster frame to a professional to see if it is acid-free or not. This way you can rest assured that your pictures would be saved for a long term.
If you want to get started with archival picture frames, you may want to opt for one with the back of an acid-free paper. By definition, an acid-free paper has base pH of 7 or slightly higher. Besides, this type of paper is free of sulfur, which makes it an ideal choice for prints that tend to degrade with the passage of time.
