Many times, when searching for a digital photo frame, people ask about the size range they come in. There is no standard size for these. You can get them as small as 1.5 inches and as large as 32 inches. These photo frames are measured diagonally, just like a computer monitor or television set. The smallest ones are made to be used as keychains, but they’re really not all that small. They will easily fit into your briefcase or even your purse, but you’re really not going to want to attach it to your keys and carry it in a pocket all day. Typically, these tiny frames have a resolution of 128 x 128 pixels.
The next size up is 2.8 inches. This one is definitely too big to be used as a keychain- but are still meant to be very portable. You can carry these in your briefcase or purse so that you can show off your family (or anything else) while you’re on the go. The resolution of this size is 320 x 240 pixels.
You can find these in a 3.5”, that resembles a conventional photo frame. This is the perfect size for a nightstand or a side table in your living room. It doesn’t take up a lot of space, but it still displays all of your pictures quite nicely.
Digital frames also come in 5.7” and 7” but these are not among the most popular sizes. The next step up is an 8” with a 800 x 600 pixel display and one with a wide aspect ratio of 800 x 480 pixels. Then, there are those that are between 9” and 12” with various resolutions.
Finally, there are the really large displays. You will find 15” displays with 1024 x 768 pixels. The 19” models come with a resolution of 1440 x 900 pixels. Then, there is the gigantic one that is 32” with a resolution of 1336 x 768 pixels.
So, as you can see, there are many different sizes that a digital photo frame can be found in. You must find the size that suits your taste and the area you have reserved for it.
