About 3X magnification. Size of the fresnel (magnifier) 190 X 120mm
Folds flat(ish), opens into a stand to put a phone.
It's a phone magnifier. Though you don't have to use it for a phone, it's just the right size for photos and postcards. Though too small for books.
There are two reasons for using this with a phone.
Firstly, photos on phones are very nice, but awfully small. The phone screen magnifier makes the photos look like printed enlargements (approx. 3X magnification).
Secondly, if you watch videos (e.g. YouTube) on a phone, holding it up level with your eye gives you sore arms. Similarly, try watching the same video while lying in bed, you prop the phone up, it keeps falling over.
