What is the exact height measurement at the tall end of the shim?

0.25" at thickest end and 0.0625" at thinnest end

Outdoor kitchen (belgard) located in st. louis/mo, but i need to level in order to place the granite countertop. is this the right product for that?

This should be fine. Thick plastic. Strong and durable.

Two concrete footings, unlevel due to slab subsidence. Need to level 2 of them 0.25" for a 12x12 deck. Strong enough?

I don’t think the shims are going to last — I’d talk with a concrete contractor.
