As Weslito said, measure your bike's top tube length, then measure your stem length (centre to centre), if you find the reach to be fine with says 100mm stem, then find a frame with the same or similar length.
If your stem is very short, it's either likely you need a shorter top tube length to compensate (unless you like it short).
