One thing to note about ordering a wide hammock, if you decide that's for you -- getting a wide hammock means the vendor will use a wide version of the material, like Hexon 1.6 wide or HyperD 1.6 wide etc. Those can be very wide, like 72-74" or so. You don't need to get the 'wide' hammock made as wide as possible though. Most if not all of the vendors will cut the wide fabric to the finished width of your choice.

For example, I got a Dutchware Chameleon hammock in the Hexon 1.6 wide but paid an extra $5 to have them customize it to 60" width. In other words, even though you specify a wide fabric, you can get the hammock made to just a touch wider than the regular version. At your height, that might be enough extra width to ensure your comfort.
