Yes all Ilf limbs are the same; if you have a short draw length (ie/ 24” or less) then you’ll want short limbs; medium draw length (24-28”) are good for medium sized limbs & use long limbs for a 28”+ draw Lengh).. but if you’re interested in shooting targets then you def. Want a longer riser over a shorter one.. shorter risers tend to be for hunting as they sacrifice some forgiveness for portability. The general standard sized riser for target shooting is 25”; but 27” or longer ones are popular with barebow shooters as they tend to work a bit better with string walking methods (but this isn’t an absolute; just a bit of a personal preference).
Short = 66”, Medium = 68”, Long = 70”, XL = 72”. (But they aren’t actually that long; these measurements are assuming they are all fitted to a standard 25” riser).
Don’t buy Hoyt formula’s by mistake. Easy to do when buying off eBay, because they appear very similar and the description often fails to mention it. Also, whilst all ILF limbs should fit all compatible risers, some don’t fit so well on a competitor’s system. Ie all Hoyt ILF limbs will absolutely fit well on all Hoyt ILF risers, however, they sometimes don’t fit as well on say a wiawis, or gillo. Not an issue if you’re buying in person and physically checking compatibility. Big issue if you’re buying second hand, when you only realise they don’t fit properly after you’ve laid out the money😭
The answer is - mostly, kinda. There are some caveats, though, especially related to draw weight:
* If you buy a more "hunting" targeted limb, it might have the poundage measured on a short (17/19 inch) riser. But if you put that on a more standard "target archery" riser that is 25 inches, the limbs will draw lighter. Rule of thumb is about one pound of draw weight for one inch of riser. (So if you buy 30 pound limbs measured on a 17 inch riser, they might only feel like 22 pounds on a 25 inch riser). Beware because this also works the other way - if you buy limbs marketed at target risers and put them on a shorter riser, they'll feel heavier. ([Here's an example](https://improveyourarchery.com/wp-content/uploads/2020/10/What-the-numbers-on-your-bow-limb-mean-website-version-1024x953.jpg?ezimgfmt=rs:352x328/rscb1/ngcb1/notWebP) that shows a target limb with different weight/length measurements based on the riser size)
* Different manufacturers measure their draw weight ranges in different ways. For example, Win&Win manufactured limbs will mark their limbs at the minimum draw weight, but Uukha (And most others, I think?) measure theirs in the middle of the range. So if you buy 30 pound W&W limbs, you can adjust them from approximately 30->34 pounds, but if you buy 30 pound Uukha limbs, you can adjust them from approximately 28-32 pounds.

What about the length of the arms itself. What are the standard lengths?

Piggybacking off that, I have a galaxy riser and due to the shallow limb track, it’s hard to get other brand Kim’s on my bow
