Buying Guide: Paper Shims For Drywall
What thickness and size should you choose?
Most drywall shims come in standard thicknesses around 1/16 inch. Ensure the shim size matches the joint gap you’re addressing. Pre-cut, ready-to-use options save time on trimming, while larger packs let you tailor each shim to fit door jambs, windows, or cabinet alignments.
Material quality and moisture considerations
Cardboard shims are lightweight and affordable but may absorb moisture. For humid spaces or areas prone to splashes, consider shims with moisture resistance or use them where dry conditions are maintained. If moisture exposure is likely, plan for replacement shims or protect the area during work.
Ease of use and cleanup
Paper-based shims designed to crumble or shed particles should be avoided for clean projects. Look for compressed kraft paper or non-shedding materials that minimize dust and cleanup after installation. Some shims are easy to trim and won’t scratch walls during adjustments.
Pre-cut versus trim-to-fit
Pre-cut shims eliminate trimming time and improve consistency across joints, but reduce flexibility for unusual gaps. If you frequently encounter irregular gaps, choose a trim-to-fit option or keep a mix of pre-cut and adjustable shims on hand.
Durability and stacking behavior
Shims should remain stable under minor pressure and not compress or “squish” during tape and mud application. Durable compressed cardboard versions are less likely to deform than lighter, looser materials, especially when you’re applying consistent pressure across seams.
Best-use scenarios
- Best for leveling baseboards, butt joints, and straightening studs in drywall projects.
- Better for cabinets, doors, and window frames where precise inset is essential.
- Choose this if you prioritize quantity and cost per shim for bulk projects.
- Avoid this if moisture exposure is unavoidable or if you require heavy-duty, non-paper alternatives.
