Buying Guide

Choose the right material

Plastic shims resist moisture and are good for tile and outdoor use; composite and cardboard shims are economical for furniture and drywall; cedar wood shims suit structural and door/frame work where compressibility matters

Match length and thickness

Longer 8" shims provide more leverage and fine adjustment for doors and framing, while shorter flats or multi-size sets give finer control for tile leveling and furniture leveling

Look for variety in a set

Sets that include multiple sizes or a high piece count let you avoid repeated purchases and handle a wider range of gaps and adjustments

Consider reusability and durability

Rigid plastic or composite shims hold shape for repeated use; cardboard shims are often single-use but cost-effective for drywall tasks

Evaluate finish and compatibility

Smooth-edged shims reduce damage to finished surfaces; choose cedar or plastic when contact with visible trim or finished flooring is expected
