I've got various different tarps of differing sizes. The biggest is a massive 3.5m x 4.5m and the smallest is 1.5m x 2m. What I don't have is a tarp of what I believe is the ideal size, that size would be 2m x 2m. The 1.5m x 2m is fine to use as an A frame but it doesn't offer enough coverage to drop the sides right down to the ground in really bad weather and keep a reasonable height.

Does anyone make a 2m x 2m quality tarp or am I going to have to make one / have one made?

Mines a whooping 3x3m DD tarp 720grams not the lightest but it in very versatile.
A smaller light will be made to suit when the time calls for it.

Massive, Whooping?? Christ my MSR Parawing could have you both pitched under it 19' x 19' Only used for base camps as a communal area, shade, etc. SilTarp1 otherwise. :D

Whopping... :D
