wheel possibilities

[Sound22Card]

My front fork INNER measurement, from the top inner surface, at the arch, to the centre of where the axel sits....is 12 inches.
The inner fork Width is 4.75 inches.
The Dia-Comp BRS 200 single pivot brake, without pads, is 59 mm Max and 39 mm Min.
The verticle distance from the brake attachment bolt centre, to the middle of the pads (middle of wheel rim) is 1.75 inches.

What sizes of wheel might fit here?

Thanks.

This is in BMX I just noticed.

Most BMX are 20".

If it was 24" it would be very obvious.

Here's a comparison.
