good question. i've never measured the width while using my TadPole in std tarp mode.
i believe it would easily provide 2 person coverage if set up in "a-frame" (std ridge) configuration.
if set up as a lean-to, one side tie outs on the ground and the opposite tie outs supported by poles/sticks, would cover 3 people.
the TadPole is 11' x 7.5' and i think the side tie outs are 7' apart.
"lean-to" 7x7 with side door/flaps.
