Furniture Restoration Calculator Tools

Repair, refinish, and restore — finishing, material matching, and structural analysis tools for bringing furniture back to life

Common Challenges

How Much Finish Do I Need?

Stripping, staining, and refinishing require different products in specific quantities. Old furniture has complex surfaces that consume more material than you expect.

Matching Wood Species

Replacement parts must match the original wood in species, grain, density, and color. Identifying unknown species and finding compatible matches is part science, part art.

Structural Joint Repair

Loose mortise and tenon joints, cracked dovetails, and broken stretchers need proper repair techniques. Calculate joint dimensions for strong, durable fixes.

Curated tools to solve your specific needs

Wood Finish Calculator

Calculate finish material needed for tables, chairs, dressers, and complex shapes. Account for multiple coats and varying absorption rates on old wood.

Old wood absorbs differently than new — calculate for extra penetration on first coats

Wood Stain Coverage Calculator

Estimate stain quantities with coverage rates by wood type and application method. Account for end-grain absorption and multi-coat jobs.

Match the original stain color while knowing exactly how much to buy

Sandpaper Requirement Calculator

Plan sandpaper needs for stripping and surface prep through progressive grits. Restoration sanding consumes far more abrasive than new work.

Stripping old finish eats sandpaper fast — stock up on 80 and 120 grit

Veneer Coverage Calculator

Calculate veneer sheet needs for patching, replacing, and restoring veneered surfaces. Account for grain-matching and waste.

Veneered antiques need precise patches — calculate waste for grain matching

Wood Density Calculator

Identify unknown wood species by comparing density, hardness, and weight characteristics against database of common woods.

Is that mahogany or sapele? Density helps narrow down mystery species

Moisture Content Calculator

Check moisture levels in old furniture and replacement wood. Ensure compatibility before gluing new parts to existing structures.

Mismatched moisture between old and new wood causes joint failures

Restoration Tips

Always test finish in a hidden area. Before stripping or applying new finish, test your products under the piece or inside a drawer. Compatibility issues are real.

Document everything with photos. Before disassembly, photograph joints, hardware locations, and veneer patterns. You will need these references during reassembly.

Let replacement wood acclimate. New wood for patches and parts should sit near the piece for at least a week. Use our moisture calculator to verify equilibrium.
