    3x3 or 4x4

    Putting in some hammock posts in the garden. I'm figuring on putting them 18" deep but not sure if I should put 3x3 treated timber or 4x4 and to what height. Any ideas?

    my posts are 4-4 36" deep and they are just clothes lines. 18" is bearly deep enough for a mail box. i would definitely go 36" no matter what u use.

    this is not mine and ignore the swing, but board/s across top will help with torque.

    3X3 will be big enough, 4X4 is better of course.

    18" no near deep enough. I would suggest 36" minimum w/concrete.

    As to height, that depends in part on how far apart you are putting them. To get the 30 deg hang angle, the farther apart the higher you'll need to be. At 12ft apart you're somewhere around 7ft high, to give an idea.

    To be absolutely sure, find a good hang spot. Set your hammock up and see if you get a good sag/lay. Measure the distance between the trees, and the height you tied off at.

    Do you tie your foot end higher than your head end? I usually go about 6" - 8" higher on the foot end.... you may want to factor that in as well.

    A 4x4 is strong enough only if it is clear and straight, and that's harder to find than you might think. Even if buried clear to bedrock, expect some bending...an overhead beam is cheap insurance.

    That thing Karl posted is lovely, but for what it costs, you could keep a kid in school for a year.
