I’m looking to build a free standing hangboard for my kids. Similar to this, only shorter:

Is there a general rule or formula to determine how long the leg supports need to be to in relation to the height to ensure the structure is stable?

OSHA says 4:1 for extension ladders.
I’d think that would be a good starting ratio for the supports.

4’ high would be a 2’ on center leg, 1’ front and 1’ back.

It only has to balance for a few seconds. It looks like yours is missing a few parts?

Have your say...
