Saddle Flap Sizing?

[PLN_Hunter-Jumper]

Hello,

Could someone educate me on how the sizing of saddle flaps(such as numbers and letters for length and width) for higher end jumping saddles works? Specific responses for brands such as CWD, Antares, etc. appreciated.

Thanks!

I realize this is an old post, but does anyone know the measurements for each size flap? TIA
