Got it.
Unfortunately there is not a good table of different lengths of arms for different brake models. Up until a few years ago, there was a good table on the internet, but that has disappeared, likely due in part to the switch to discs.
I have 85mm V brakes on my Airnimal. Tires are at most 40mm wide, no fenders. These are commonly referred to as mini-V brakes. Similar to these:

I have 110mm V brakes on my heavy duty touring bike, a Thorn Nomad Mk II. Tires are 57mm wide, and fenders. And the brake cable just barely rubs on the fender. Similar to these:

I wanted to make sure that the OP got ones that would work on his bike with fenders.
Some (including me) will run road (short cable pull) brake levers with mini-V brakes, but not the longer arm V brakes which require longer cable pull brake levers.
Perhaps the size on the above links of 20.5 to 36.5mm for each of those is the size you refer to when you say long or short? But it appears that this measurement is the same on each of the Tektro brake models that I looked at.
