How are base cabinet gables sized compared to wall cabinet gables?

Standard kitchen base cabinets are 34-1/2" tall and 24" deep, usually featuring an integrated 4" x 3" toe-kick notch and open-top stretchers for countertop attachment. Wall cabinets are typically 12" deep with solid enclosed top and bottom decks.

What is the clearance setback for adjustable cabinet shelves?

Standard shop practice deducts 1/8" (3.2mm) from the cabinet interior core width so shelves slide smoothly between gable shelf pins without scratching. The shelf depth is setback 1/4" (6.4mm) from the front edge to leave room for door bumpers.
