Buying Guide

Choose material for the task

Plastic shims resist moisture and are reusable for tile or outdoor projects, while cardboard or composite shims work for drywall and furniture where compressibility or low cost matters

Match thickness and size

Stackable or multi-size sets let you build precise thicknesses; look for lengths and widths that fit door jambs, window frames, or tile edges you commonly work on

Consider pack count vs. price

Higher-piece kits reduce repeat purchases for frequent use; evaluate how many 1/16–1/8-inch increments you’ll need based on typical projects

Check compatibility with leveling systems

Some plastic flat shims are designed for tile-leveling or trim work—confirm the shim shape and stiffness match the tool or gap you’re adjusting

Prioritize durability and reusability

Rigid polypropylene or composite shims maintain shape under load better than thin cardboard, making them preferable for structural or repeated adjustments
