Best Woodworking Planner

How I Actually Plan Woodworking Projects (Without Going Mad)

I spent years building things without a formal plan, which means I built a lot of things wrong. The turning point was buying the wrong board twice because I couldn't keep track of my actual dimensions versus what I wrote down. Since then, I use a structured Best Woodworking Planner for every project that involves more than three cuts. It's not a single piece of software. It's a workflow template, usually spreadsheet-based, that breaks a project down into: materials list with rough cut dimensions, finished piece dimensions, cut lists, joinery details, finish schedule, and a shopping list for hardware. Some people make their own from scratch. Others use free templates you can find online. The one I use has seven tabs. The first one is the bill of materials, where I list every board I need, the rough size, the finished size, and the yield I expect from each piece. The second is the cut list, which translates that into actual saw cuts with numbers so I'm not guessing at the band saw. The third is hardware. The rest are for notes, sketches, and a running cost total.

I've also used a few dedicated apps over the years. SketchUp with a cut list plugin works well for complex joinery but takes too long to set up for simple work. Free plans like those from Rockler or Ana White come with their own cut lists, which are helpful if you're following someone else's project exactly. But when you're doing custom furniture, you build your own planner from scratch. That's where most people get stuck.

The Process I Actually Use

Step one is always a pencil sketch. Not a rendering. A messy drawing with rough proportions. This keeps you from spiraling into CAD before you know if the thing will even fit in your space. Step two is writing down the finished dimensions of every sub-assembly. A bookshelf becomes: two sides 72 x 12, five shelves 11.5 x 12, one back panel 72 x 48, top 12 x 30. You write those down before you think about wood species or grain matching. That order matters. Step three is converting those numbers into a cut list. This is where people fail most often. You take each finished dimension and add the material you need to remove for your joinery and surface planing. A shelf that needs to be 11.5 inches wide after planing might start as a 12.25 board if you're resawing or jointing both faces. A dado that's 3/4 inch wide means the corresponding side piece gets trimmed by that amount. You track every deduction.

Step four is laying out the cuts on board lengths. This is the nesting step. If you have three shelves at 11.5 inches and one at 15 inches, you figure out which boards to cut them from so you waste as little as possible. I do this by hand on graph paper. Some people use software like CutList Optimizer, which handles it faster but requires an initial investment of time learning the interface. Step five is the materials purchase list. You convert everything to actual lumber dimensions. That 1x12 shelf isn't 11.5 inches when you buy it. It's 11.25 inches at the store, maybe. You buy 10% extra on every board type. Always. At minimum.

The Problem I Keep Running Into

About a year ago, I planned a live-edge live-slab dining table and completely underestimated the warping that happens in a 10-inch wide slab over six months. I had the planner down to the dollar and the cut list was perfect. I didn't account for the fact that a slab this wide will cup toward the bark side once it acclimates in a heated shop. I made the legs too short on paper because I was cutting to the dry width. When the wood moved, the tabletop was uneven by about three-eighths of an inch across the span. The fix was sanding the high spots and adding shims under the table base, which added two weeks and a bunch of frustration. The lesson was simple: I should have accounted for moisture content changes in the planner instead of assuming the board would stay flat. That's the thing about planning. You can nail the math, but wood itself is the unpredictable variable. The planner doesn't solve that. It just makes the math visible so you can see where it falls apart before you cut.

Common Mistakes People Make

Not accounting for tool thickness. If you're cutting on a table saw with a 1/8-inch kerf and you need ten pieces from one board, that's nearly three-quarters of an inch of material gone to dust before you even start assembling. I stopped ignoring kerf after I ruined a mahogany face frame by not counting it in. Mixing up rough and finished dimensions. This happens all the time. You write "24 inches" for a board and mean finished length, but you actually cut it to 24 inches rough. Now your assembly is two inches short and you can't fix it without ordering more wood. Always label everything clearly as R for rough and F for finished. It takes two seconds and saves hours later. Planning for one species and buying another. Hard maple shrinks differently than red oak. If your design assumes a certain amount of movement and you swap species, the joinery might fail. I learned this the hard way on a cherry cabinet that I originally designed for white oak. The drawers bound in winter because cherry moves more than oak across the grain.

Skip the hardware list until the end. Most people don't list hinges, pulls, and screws until they're halfway through the build. Then they realize they need half-blind dovetail pins that require a different router bit than what they bought, or they need 2-inch pocket screws but only have 1.5-inch ones. Write the hardware list in step one alongside the sketch.

Free Tools I Recommend

For the spreadsheet itself, Google Sheets works fine. I've shared templates with people and they usually modify it to fit their workflow. The key fields are board length, board width, quantity, rough cut length, finished length, and yield percentage. If you're doing a lot of work, setting up conditional formatting so that boards over a certain length trigger a warning flag helps catch errors before they become expensive ones. For cut optimization, CutList Plus (desktop app) and CutList Optimizer (web-based) both handle nested cut lists efficiently. They aren't perfect, but they reduce the trial-and-error that eats up an afternoon. For visual layout, SketchUp Free is adequate for basic projects. If you need more precision with joinery diagrams, I use SketchUp Pro for anything involving mortise and tenon or box joints. The free version doesn't handle plugins well, which matters if you want to generate a cut list automatically from your model.

When a Planner Actually Helps vs. When It Doesn't

A planner makes a real difference for anything that requires multiple materials, complex joinery, or a budget above a couple hundred dollars. A simple cutting board doesn't need one. A bookshelf with adjustable shelves? Maybe not. A cabinet with face frames, dovetail drawers, and a custom finish? Yes, absolutely. The planning process itself takes about 15 to 45 minutes depending on project complexity. That time pays for itself if it prevents one mistake that costs $80 in wrong lumber or two hours of rework. It usually does.

What No Planner Can Fix

Wood movement. Grain direction. The fact that your table saw blade is slightly off calibration. A planner gives you a map, but it can't predict how a particular board will behave once it leaves the store. The best planners include a note section for recording surprises after you've built the thing. That's where the real learning happens.
