Planning Workflow

Follow these steps with the right calculators at each stage

1

Select & Estimate Material

Choose your wood species based on the balance of appearance, workability, and cost your project demands. Walnut runs $8-14 per board foot, cherry $6-10, maple $5-8, and oak $4-7. Calculate total board footage with at least 20-25% overage — you will lose material to defects, grain matching, and cutting waste. A dining table typically needs 30-40 BF for the top, plus another 10-15 BF for legs, aprons, and stretchers. Check density to predict weight: a 6-foot walnut table top at 3/4 inch thick weighs approximately 35-45 lbs before finish.

2

Design Joinery

Select joints based on the structural demands and visual style of each connection. Mortise and tenon joints are the backbone of frame construction — set mortise depth to 2/3 of stock thickness and width to 1/3 of stock width. For dovetails on drawers or case pieces, use a 1:6 pin-to-tail ratio in softwoods and 1:8 in hardwoods. Dado and groove joints at 1/3 stock thickness are ideal for shelving and case dividers. Our calculators generate exact dimensions and saw settings for each joint type.

3

Plan Assembly & Fasteners

Glue-ups are the most stressful part of furniture making — plan them in advance. Calculate total glue needed based on joint surface area: expect roughly 6-8 square inches of coverage per ounce of PVA glue. A typical table requires 8-12 oz total. Plan your glue-up sequence: which joints get assembled first, how many clamps you need, and what your open time is (15-20 minutes for standard yellow glue, 30+ for extended formulas). For supplemental fasteners, count pocket screws, dowels, or figure-eight fasteners needed.

4

Calculate Finishing

Furniture finishing has enormous surface area when you count all faces: a dining table plus 6 chairs might have 80-100 square feet of surface to finish. Budget for 3 coats of topcoat on all surfaces, with sanding between coats at 320 grit. If staining, calculate stain coverage separately — end grain absorbs 3-4x more stain than face grain. Track sandpaper needs across grit progressions: 120 for initial surfacing, 150 after raising the grain, 180 and 220 for final smoothing, 320 between finish coats.

5

Set Your Price

If you are selling this piece, pricing is critical to sustainability. Start with material costs (calculated in steps 1-4), then add labor hours at your true shop rate (including overhead — most custom furniture makers need $35-75/hour to be viable). A dining table typically takes 40-80 hours depending on complexity. Add overhead allocation (shop rent, utilities, insurance, tool depreciation), then apply your target profit margin: 30-50% is standard for custom furniture. Our pricing calculator breaks all of this down so you present a confident, defensible price.

Custom Furniture Pro Tips

Mill all your lumber in one session. Joint, plane, and rip all stock to final thickness on the same day. This ensures consistent thickness across all parts and lets the wood acclimate to its milled state before you cut joinery.
Always design for wood movement. A 12-inch wide solid panel can move 1/8 inch or more across the grain seasonally. Use the expansion calculator for every glue-up wider than 6 inches, and always orient breadboard ends with elongated screw holes.
Test your finish on the actual species. Cherry, maple, and pine all react differently to stains and topcoats. Apply your planned finish to an offcut before committing. What looks great on oak may look terrible on cherry.
Price your time honestly. Track actual hours on every project for at least your first 10 commissions. Most furniture makers underestimate labor by 30-40% until they have real data. Use our hourly rate calculator once you know your true time investment.
