Be cool to each other. We'll welcome most occult themes, it's okay if you stray from witchcraft a bit.

What’s an average sized witch?
Probably one with under about 980 Newtons weight
i mean you have to account for air resistence and you need enough lift to actually fly. and we are not talking about the best aerodynamics here.
About the weight of a duck.
I got better.
Assuming that's it's just the normal force of Earth's gravity at work on the witch, it's just a case of working Newton's second backwards with the gravitational "constant" acceleration ≈ 9.8 m/s²:
F = ma
980 N = m × 9.8 m/s²
980 / 9.8 = (m × 9.8) / 9.8, units omitted for text clarity
100 kg = m
In other words, op is assuming that an average size witch masses approximately 100kg (or about 220 lbs in fingers, knees, and toes units).
That's not enough for flight, only enough to nullify gravity. It makes sense OP would leave some trust for acceleration
They'll flap their arms for propulsion
Using Hocus Pocus as a data sample, Bette Midler is the average sized witch.
