Buying Guide

Choose the right material

Composite and plastic shims resist moisture and compress less over time, while cedar or wood shims are cheaper and can be trimmed or driven in for fine adjustments

Pick appropriate length and thickness

8-inch shims give more leverage for large furniture, while sets with multiple thin sizes let you stack and fine-tune level and gap control

Consider pack count and project scope

Higher-count packs are more cost-effective for multiple jobs or professional use; smaller sets can suffice for occasional household leveling

Look for stable, noncompressing options

Materials like composite or polypropylene hold shape under load better than soft wood, reducing the need for readjustment

Assess trim-ability and usability

Wood shims are easy to cut or wedge for custom fits, while molded plastic or composite shims often include consistent tapering for repeatable use
