We have a paved runway but that really doesn't matter. It's 30 feet wide by 450 in length. It is fine for glow planes up to about 20cc and gassers up to 40% scale but not for jets. Novice pilots can have difficulty because of the width and if I were designing a new field I'd look for a minimum of 40 foot width for either grass or pavement. And keep the 'run off' areas surrounding the runway clear as any irregularities there can cause landing gear damage.

Best of luck over there.
