I cant stand being in a blind that I can not stand up comfortably and shoot...although most were made to shoot sitting down in a chair...standing will bring bow higher and there has been many a bowhunter with shots ruined by bow limb hitting ceiling or arrow bouncing off window frames of blinds...
I am only 5'9" and still have to dig a hole to stand in most ...lol
Ameristep many a few that are in that 6ft range ...
one being the Ameristep's "Penthouse" which is 78" wide and a generous 90" high.
The Bone collector is also 6'4"

Another is the Barronett Big Mike Ground Blind 75" x 75" x 80" or 6'8"
The Hub style can cost three times more but a whiz to set up and take down...some of the Pop-up styles are easy to set set as basically you just toss it and its up....the real challange is getting it broke back down with fancy twists....nothing funnier than seeing a bowhunter at dark coming back to camp trying to tote a six foot circle of a blind...
