One mast, four corners, a clear floor
A 4x4 spans its whole 16 m² from the corners with a single mast overhead. Nothing stands in the middle of the floor and nothing lands mid-wall. Furniture is laid out to the room rather than around a leg, and every one of the four 4 m sides is an unbroken run.
Square or rectangle at the same area
A 4x4 covers 16 m² and a 3x6 covers 18, so the two are close on paper and different in use. The rectangle gives 6 m of frontage and 3 m of depth. The square gives 4 m in both directions and four sides of equal length. The difference is shape, not area.
Apex 4.09 m or 4.27 m
COL440 stands 4.09 m to the point, 72 cm above a 3 m CO. ZP440 stands 4.27 m, and both stand 2.55 m to the roof edge. The ZP profile is specified as a taller leg, roof spike and valence, giving a larger surface for branding.
Ballast on four corner legs
Plan 49 kg per foot against a 30 mph gust, rising to 81 kg if the site sees 50. Across four feet that is 196 kg at the low end and 324 kg at the high, holding down 16 m² with no intermediate anchor point to help. For the full 60 mph rating LP Tent specifies 130 kg per leg on hard standing, or stakes with 150 kg of pull-out on soft ground.
The bag gets longer here
COL440 packs to 2.04 m and ZP440 to 2.08 m, against 1.55 m and 1.60 m for the 3 m sizes: roughly 48 cm more packed length, and the figure to check against your load space. Weights are 34 kg and 45 kg.
16 m² of room, and four ranges that build it
The space calculator gives 21 standing, 14 in seated rows or 8 at dining tables at normal circulation. CO and ZP publish full figures; Pagode and GP are made at 4×4m as well and their specification comes with the quote. Where the roof profile is part of the look rather than a working cover, the Pagode is the one to ask about.
Sixteen metres of perimeter, four equal sides
Every side is 4 m, so walls, doors and printed panels are interchangeable between them. The ZP and Pagode sliding-wall system with a bottom tension bar holds a 4 m panel flat.
