Pocket hole screw size for 3/4" material
Three-quarter-inch is the workhorse thickness for pocket holes — 3/4" plywood and nominal 1× lumber are what most cabinets and furniture are built from, so this is the size most people are actually asking about.
Here's the pocket-hole screw length for 3/4" material, and the thread to match your wood.

What 3/4" stock is for
3/4" stock is the default for cabinet boxes and face frames, bookshelves and shelving, table and bench aprons, and most furniture carcasses — anything built from 3/4" plywood or nominal 1× boards.
It's the thickness the standard jig setting and the common pocket screw length are designed around, which is why it's the most forgiving thickness to start with.

Common questions
What length pocket hole screw for 3/4" material?
For 3/4" (19 mm) stock, use a 1¼" (32 mm) pocket screw. Pocket-hole screw length is set by the thickness of the piece the pockets are drilled in.
Coarse or fine thread for 3/4" material?
Match the thread to the material: coarse-thread pocket screws for softwood and plywood, fine-thread for hardwood and MDF.
Do pocket hole screws need a pilot hole in 3/4" stock?
No — pocket screws are self-tapping, and the jig's stepped bit drills the pilot in the first board. Just set the jig and the drill-guide collar for 3/4" material.
