Depending on what height is comfortable for you choose from heights between 14 and 19 inches above the ground.
Built in bench dimensions.
Built in deck benches often are used to define the perimeters of a deck.
Bench seats tend to sit somewhere around 16 inches high.
How deep are benches.
Bench length per person will of course vary depending on the size of the people involved.
That should do the trick.
A bench can be the full width of your table or slightly less long so that it can be tucked underneath the table.
I have used many different heights for my clients depending on how tall they are and the purpose for the bench.
On low decks deck benches can be plain seats with no backs.
Use an hd36 high quality foam or better yet a lux foam r regular.
This affects both how many people it can seat and how it relates to your table.
Although this is the average range the height of a bench is dependent on its use.
A bench between 42 and 52 inches in length will seat two adults comfortably.
However if the edge of your decking walking surface is more than 30 inches above grade then your built in bench has the building code obligation to act as a fixed railing system too.
Benches can have a depth anywhere from 15 20 inches 38 51 cm although the typical bench used for dining is considered to be around 17 inches 44 cm.
Typically a 17 high rough bench size and a 3 cushion is very comfortable as it will compress to approximately 18.
