quickie question re: bit for welsh A

[Jericho]

as title please... need to get a bit quickly!
Pony is 11.2hh welsh a. I think my last Welsh A was a 4.5 inch but cant remember! So all of those with little welshies what size bits (jointed eggbutt snaffle preferably) do you have yours in just to give me a quick start? Thanks

my 11h 1" wears a 4.25 & my 10h 3" wears a 4.75 cos she got a big mouth lol

4.5 inch fitted nicely but he could go a bit smaller without hurting him.
