I made mine 30", which is a standard table top height. It is perfect for using that kind of chair or a kitchen style chair, but if you plan to use a barstool to sit on then I would make it 42".

I actually have some thin sections of carpet to put on it to make it more comfortable but havent done it yet.

I have plans on making mine longer, or adding a higher section to it so I can also reload either standing or from a barstool. Just one of those many projects that works now and keeps getting put on the backburner, just like the gun room ::).
