Pocket Pony – how large is your arena? If you could make it bigger, would you want wider or longer or both?
Thanks![/QUOTE]
I would consider going wider and not insulate, if you are watching pennies.
Later, if you want to insulate, get that spray on foam that they spray in commercial buildings and is rated even higher than regular insulation is.
You can save a ton up front by not insulating, go there later if you really need to do so.
Go as wide as you can manage, it is worth it, shorter length now if you have to, you can add later.
A local stable has a 100’ x 100’ and left space to expand to 150’, but never needed to, they train and even have clinics there and it works for them.
Here are some ideas of arena sizes for different purposes.
You may want to look thru their web site for other ideas:

Here, we hardly ever have any weather from the East side, so we left that side open and we still have not had any rain or snow hardly ever get in there.
Our South side has an overhang for an aisle and overhangs, but is open now because we don’t have the stalls in there yet.
We will have a good 4’ of screens above the stalls for airflow, with screens to keep any rain or snow out.
