What height concrete gate posts do I need for a 4 foot high gate

gate-postgates

The gate is 4ft high by 4ft wide for a garden path and is a standard quality metal gate, so not very heavy.

Best Answer

The post should be 4 feet high above ground and deep enough to be set into concrete below the frost line. A 4' hole (8' post) should be more than sufficient. Probably overkill, in fact, but wouldn't go any less than 6' total, 2' below grade, and if you're in the north, definitely go deeper.
