That's quite standard, the manfrotto 561BHDV video monopod that's been a longtime staple used by many (and myself haha) does something like 76cm folded, 200cm max. Being able to lock sounds super useful.
Cathay Photo has a demo model which I tried out for a few minutes. First impressions : Pretty heavy and the video head is a bit stiff so not easy to get a smooth pan. Pre-order only at $4xx
