Standover (crotch clearance) is the height of the top tube above the ground: the clearance left between your crotch and the frame when you straddle it with your feet on the ground. If it's lower than your inseam, you can plant your feet without hitting the tube. With sloping frames and dropper posts, standover dropped so much across all sizes that it stopped ruling sizing. Today it's a secondary figure: reach decides the fit.
For decades it was the first thing you checked when picking a bike. Today it's almost never the problem — but it's worth knowing when you should still look at it.
"Can I reach the ground without jabbing myself on the tube?" That was the test of all time. Modern bikes pass it with room to spare almost every time, so the question lost importance — but not entirely.
Standover is the vertical distance from the ground to the top tube of the frame. It indicates how much free space you have above the tube when you stand straddling the bike, stopped. If your inseam (your body's measurement) is greater than the bike's standover, you have clearance and can plant your feet safely when you stop.
Two changes dethroned it. First, sloping frames: the top tube tilted way down, lowering standover at almost any point. Second, dropper posts, which let you raise the saddle very high on compact frames. The result is that today almost any reasonable size leaves you plenty of clearance, so standover went from being a decisive filter to a figure that rarely rules out a size. Reach took its place as the fit criterion.
Standover matters again in specific cases: if you're right on the edge between two sizes, if you have short legs for your height, or if you ride technical terrain where you stop, start, and put a foot down often and want plenty of margin not to hit yourself. In those cases, confirm that the standover leaves you comfortable clearance. In normal use, it's enough that it isn't clearly above your inseam.

If you're right on the edge of a size, have short legs, or ride technical terrain stopping a lot. Otherwise, it's secondary.
