in Phoenix backyards aren't terribly large. we have a decent sized yard for AZ where with a 40 x 10 foot pool placed 7 feet from the back wall of our house, 13 feet and 16.5 feet from the sides, our kids (6, 7, 10) can still ride their bikes in the backyard and we have a little room left over for chickens. i want to be able to swim laps and i know 40 feet isn't a lap pool, but it's longer than any pools i've seen in AZ. we want to play volleyball, basketball, exercise, lots of exercise/swimming and some play on the baja shelf. I just signed the contract on saturday so have less than a week to decide about layout. most pools out here seem to be 12 or 13 feet wide on the narrow end. will 10 be enough for our crazy boys to not be cracking their heads on the side of the pool and for us to feel like we have enough space to move around? i'd hate to regret going too small. the only factors with going "too" wide are i'm thinking pool may not look as stunning and unique, each foot is an extra $735, and i'm taking up more yard space the wider i go. i was excited to save my grass.
