It's 1.5m long and 20cm wide (so 75cm when folded). When travelling it just goes in the boot behind the RIB bed along with chairs, canopy, etc, etc. We're SWB.
If I was making it again I might add 4 or 5 more centimeters so that the angle can be less steep, but it works fine and it's the minimum size possible. Hinges are good quality heavy stainless steel flat hinges.
