You've got one wall, one ceiling, and a rendering that doesn't know either number. Your tape says 93¾; the picture says trust me. Guess wrong and you pay for it in a second trip, a restocking fee, or a filler you end up cutting by eye in the driveway.
Type your two numbers and you get back the box widths that actually close — the filler sizes, the height stack that lands on your ceiling, and the exact words to type into the store's search. Before you fall in love with a layout the store doesn't stock.
Stock cabinets come in a handful of widths. A wall comes in one. The run is the set of stock boxes that fills your wall to the sixteenth — fillers where the wall isn't square, a height stack that lands on the ceiling.

Last Saturday: a 93¾-inch mudroom wall, a nine-foot ceiling, a rendering that looked finished, and an AI chat that had invented a “window nook” off two numbers on my sketch. The tape didn't care about the picture. The math closed on its own — 1⅞ + 30 + 30 + 30 + 1⅞ = 93¾, 90 + 18 = 108 — and then the store's house brand turned out not to make that pantry in 30 wide. A different line did. The rendering wasn't a plan. The tape was.
12 to 36 in 3-inch steps. Your wall gets spelled with those, plus a filler each end for the inch and a half no wall gives you square.
Uppers match the widths below so every seam lines up. Tall plus upper reaches the ceiling: an inch short is scribe, four is crown.
One bay, open — drawers below, wall above. Never across a seam.
Inches. Ceiling at both ends and the middle; type the smallest.
Skip if the wall is blank. Otherwise outside edge of the trim.
Best first, under three inches of slack. Tap one.
Tall plus upper. Tap one.
Search the tall first — if the line lacks that width, the run re-spells.
Most problems are who-you-know. Name one person who has hung cabinets.
Now make the call — ask: “what would you check before you ordered?”
Washington or Dakota County, Minnesota. Off-market, or straight from the owner — I'm the buyer, not a middleman passing it along. Woodbury, Cottage Grove, Hastings, Stillwater, Eagan, Inver Grove Heights, Lakeville.
If that's you, or you know somebody quietly thinking about selling, I'll lay out your options — all of them, including the ones I don't make a dime on. Nothing to sign, no walkthrough unless you ask.
That was free and nothing here sits behind an email. If it was useful, here's the whole exchange: send it to one or two people who'd use it too. That's it. I'm trusting you with it, you pass it on.
Want the next one before anyone else? I'm building an interest list — no selling, no sequence, your address goes nowhere. Exactly what that means, in plain words.
The list itself isn't open yet — I'm still setting it up, and I'd rather say that than put up a box that doesn't work. The ask above stands either way, and it's the one that matters. If you want to tell me what to build next, my DMs are open.
Free. This tool asks you for nothing — no gate, no email, no analytics. When your run comes back in stock, DM me the wall.
