There will be a bit more than size to consider. There are also different types. The board will tell you that you can't post pictures, but try anyway. The photos will upload to your album and someone will help you post it in this thread.

As Chuck M said there is a lot to consider. However if you are looking to post photos just get the needed 10 posts by posting in the many currently active threads and get involved with the forums you will be able to post pictures in no time at all and will learn and get to chat about bikes which is always awesome. It is the better way to go because it encourages you to check out these awesome forums and sub-forums and get involved otherwise it is a decent amount of work to just post a single question and leave and miss out and so much awesome discussion and content.

Veganbikes makes some good points. And searching the forum for fork sizes etc. and asking questions in some of the threads where fork selection is discussed will get you to the 10 post threshold in a couple of days.

Tell us everything you can about the frame. Probably you can find the site of the manufacturer and possibly find geometry information there. If not, there might be info out there on a third-party site ... I know there used to be a fairly comprehensive frame geometry site. If nothing else, find a similar style of bike in about the same size and measure the fork.

Also I say it often and people forget or miss the post but if you are using someone's forum handle if you put the @ symbol in front of it it will tag them and let them know you have mentioned them. Basically you put the symbol and the list of names (and any icons they use) pops up and shows up like this Chuck M but that person gets notified and in case they might miss it.

To clarify what others have posted, the frame geometry determines the fork you need. Your best bet is to find the manufacturer's website and see what was on the frame originally. From there, you can increase the offset to make it handle a little quicker or decrease offset to make for a slower steering response. We're talking a few mm in either direction, but you really need to know what the frame was designed for.
