One evening, a tape measure, and the samples in the basement. Print this, write in the boxes, photograph the pages, and hand them back — the numbers flow straight into the already-built size guide. Created July 8, 2026 · owners Trevor + Haley.
website/snippets/size-chart.liquid: Women XS–XL and Men S–XXL chest + length; Kids age/height/chest; Baby age/height/weight; the Accessories section currently reads "final dimensions at launch"). It also captures per-SKU weights, which the packaging & shipping plan needs for rate strategy. This is the single remaining hard founder blocker in the founder checklist.
| Measure | How |
|---|---|
| Chest (pit-to-pit) | Straight line from armpit seam to armpit seam, 1″ below the armhole. This is the half-chest; write what the tape says — I'll double it for the garment circumference. |
| Length | From the highest point of the shoulder (where the shoulder seam meets the neck) straight down to the bottom hem. |
| Shoulder width | Straight across the back, shoulder seam to shoulder seam. |
| Hem width | Straight across the bottom opening, edge to edge (half measurement, same as chest). |
| Armhole depth | Straight line from the top of the shoulder seam down to the bottom of the armpit. |
| Weight | Kitchen scale, in ounces (or grams — note which). One reading per size. |
| Label size | Chest / pit-to-pit (in) | Length (in) | Shoulder (in) | Hem width (in) | Armhole (in) | Weight (oz) |
|---|---|---|---|---|---|---|
| XS | ||||||
| S | ||||||
| M | ||||||
| L | ||||||
| XL | ||||||
| (other: ___ ) |
Fit intent — circle one and add a sentence (this becomes the chart's fit note + PDP fit line)
Runs: true to size / relaxed / oversized · Between sizes: size up / size down · Layers over a sweater: yes / no
Worksheet 2| Label size | Chest / pit-to-pit (in) | Length (in) | Shoulder (in) | Hem width (in) | Armhole (in) | Weight (oz) |
|---|---|---|---|---|---|---|
| S | ||||||
| M | ||||||
| L | ||||||
| XL | ||||||
| XXL | ||||||
| (other: ___ ) |
Fit intent
Worksheet 3The kids chart is keyed by age band + height + chest — so besides the garment numbers, decide the age band each label size is meant to fit (the "fits ages" call is yours; heights I can fill from standard growth ranges once the ages are set).
| Label size (as printed) | Chest / pit-to-pit (in) | Length (in) | Shoulder (in) | Weight (oz) | Fits ages (your call) |
|---|---|---|---|---|---|
Fit intent (e.g., "roomy — buy the age, it lasts two seasons")
Worksheet 4| Size | Inside circumference (in) | Brim width (in) | Crown height (in) | Weight (oz) | Fits ages / head (your call) |
|---|---|---|---|---|---|
| Baby | |||||
| Kids | |||||
| Adult |
Inside circumference: run the tape around the inside of the crown where the head sits. If there's an adjuster (toggle/velcro), measure at its loosest and tightest and write both ("20–22″").
Worksheet 5| Style | Frame width (in) | Lens width (in) | Bridge (in) | Temple length (in) | Weight (oz) | Fits ages (your call) |
|---|---|---|---|---|---|---|
| Infant | ||||||
| Toddler |
Frame width = the widest outside edge-to-edge across the front. Temple = arm length, hinge to tip.
Worksheet 6| Measure | Value |
|---|---|
| Open dimensions (confirm the 135 × 135 cm spec against a real unit, in inches) | |
| Folded dimensions (L × W × H, in) | |
| Weight (oz or lb) |
| Item | Dimensions (in) | Weight (oz) |
|---|---|---|
| Scarf (L × W, flat) | ||
| Eye mask (W × H + strap: stretched / relaxed) |
The site's chart shows body chest ranges ("M fits chest 38–40″"), not garment numbers. Once the garment measurements exist, the mapping is garment chest minus wearing ease. Simplest honest method: each of you puts on your true size, then the size up, and answers: does your true size fit the way the brand intends? Write what you'd tell a friend:
That plus the garment numbers is enough for me to derive the full body-range columns credibly and set the "between sizes" advice. (These same two lines become the PDP's model_fit note once the on-model shoot happens — "Trevor is 6′1″ and wears an L.")
Faster per garment than the tape, and the photos stay measurable forever — when a number nobody wrote down is needed in October, we re-measure the photo, not the basement. Use it for the vests; the tape worksheets above still carry the accessories (circumference and 3-D shapes don't photograph flat) and the two calibration garments below.
| Item | What to buy | Why this one |
|---|---|---|
| The grid | Foldable cardboard pattern-cutting board, 40″ × 72″, printed 1″ grid — sewing-notions aisle or Amazon; Dritz "Superboard" is the classic (~$20) | Biggest grid per dollar and the only cheap surface a men's XL vest fits inside with margin. (A 36×24″ self-healing rotary mat is sturdier but the vest overhangs its short side — wrong tool here.) |
| Landmark dots | Round color-coding dot stickers, ¼″–⅜″, in a dark color (Avery-style, ~$5) | They mark exactly where the "armpit point" is — the biggest source of disagreement in any measuring method. Dark reads against ivory garments; don't buy white. |
| Plane check | Any rigid ruler or yardstick you own | Laid on the garment in one frame, it verifies the scale at garment height, not just board height. |
| Hold-down | Painter's tape | Tapes the board corners flat to the floor — a bowed board bends the grid. |
The whole vest line — every size, both colorways spot-checked — is roughly 20 minutes. Back side too if you have the patience (one flip, one more frame), but the front carries every chart number.
Tape-measure two garments fully using Worksheets 1 and 3 — one women's vest, one kids vest — the same pieces you photograph. I derive the photo measurements independently, then check them against your tape numbers. If they agree within ¼″, every other photo is trusted; if not, we find out why before any number touches the site.
snippets/size-chart.liquid with the real numbers, both units; (2) replace the Accessories "final dimensions at launch" line with real dimensions; (3) remove the "Sample measurements" disclaimer; (4) set each product's custom.size_category routing if any is off; (5) carry the weights into the packaging & shipping plan's rate math. One evening of tape measure → the last hard launch blocker in the checklist closes.
