I was taught by local growers in the Niagara Peninsula:

Early peaches, thin to 10-12 inches, except for cultivars especially prone
to split pits.
Midseason (Redhaven - Vanity) 8 inches
Late (Madison) 5-6 inches

I used to let peaches grow a little thicker on strong wood in the tops
exposed to sun, and I would thin harder in shady parts. Row end trees can
be loaded a little heavier. A heavy crop load slows ripening and increases
the number of pickings required as well as decreasing size.

Remove peaches likely to bump twigs, branches or other peaches, or stress
their attachment to the tree, as they grow and get heavier. Save the
peaches that won't make trouble.
