What this template builds for you

Dining chairs are woodworking's watershed project — plenty of people can build a stool; very few build a great chair. The difference: chairs need back rake (5–8° lean), splayed rear legs (so the chair doesn't tip when you lean back), seat slope (front-low-back-high, so you don't slide off), and tapered legs (visually light).

The algorithm bundles all four. Enter "seat 45 cm, back 80 cm, 6° rake, rear-leg splay 8°" and the system computes the rear-leg true length (with compound-angle math), back-slat spacing for 5 rails, and the joinery positions where each of the four legs meets the seat frame. The drawings ship with a back-curve detail, true-length leg dimensions, and table-saw setup values — cut to the lines and you get a chair you can sit in for two hours without lower-back pain.

Build 6 for a dining set, 1 for an office chair, 4 for a café — this template is the ceiling test for residential woodworking.

Who this template suits

✓ Recommended for

· Intermediate-to-advanced builders ready for "real furniture"
· Opening a café / B&B that needs 4–6 chairs
· Upgrading the dining-room atmosphere

× Not for

· No mortise-and-tenon experience yet — build a stool first

Parameters you can adjust

The algorithm auto-computes dimensions, joinery, and material usage.

Seat / back height

Seat 42–45 cm, back 80–90 cm

Back rake

5–8° is the comfort sweet spot; > 10° is not a dining chair

Rear-leg splay

Usually 6–10°; prevents tipping when leaning back

Back rails

3–7 horizontal rails; more rails = more visual mass

Dining chair common dimensions

These numbers come straight from this template's adjustable ranges and defaults, so they update whenever the template does.

Dimension	Adjustable range	Template default
Length	up to 600 mm (60 cm)	450 mm (45 cm)
Width (depth)	up to 650 mm (65 cm)	450 mm (45 cm)
Height	up to 1100 mm (110 cm)	850 mm (85 cm)
Seat height	350–550 mm (35–55 cm)	450 mm (45 cm)
Back rake (°)	0–15 °	5 °
Armrest height	150–280 mm (15–28 cm)	200 mm (20 cm)

Main dimensions list only the upper bound: the template has no meaningful lower limit. Values in mm with cm in brackets.

How to pick your sizes

Seat height 42–45 cm: thighs level, feet flat, matched to a 72–75 cm dining table.
Seat depth 40–45 cm with two or three fingers of clearance behind the knee; seat width at least 40–45 cm.
Back top around 80–90 cm from the floor, lumbar support 15–25 cm above the seat; armrests 20–25 cm above the seat.

When you'd build one

Dining set of six

Build six identical chairs around a dining table — full set runs 50% less than IKEA at twice the quality.

Café fit-out

New shop needs 12 chairs; quotes come in at $260 each — your in-house material cost is $50 per chair.

Home office

A chair sized to your body — store-bought office chairs are universally too tall.

Heirloom build

Walnut dining chair that your kids will still use as adults — store-bought can't deliver that.

5 preset variations

Swap styles in one click — no need to re-adjust every parameter from scratch.

Straight-back, straight-leg

3 vertical back rails, square upright legs — the canonical dining chair, good for a first build.

Slat-back, splayed-leg

4 horizontal back rails with splayed rear legs — ergonomic, comfortable for long sits.

Windsor

Turned spindles in a fan back — English country / café classic, fine joinery.

Plank-back, tapered-leg

Single wide back panel with tapered legs — Hans Wegner Nordic feel, visually crisp.

Curved-back

Gentle bent back that hugs the spine — advanced bending work but a comfort upgrade.

FAQ

What's the hardest part of a chair?+

The rear legs. They take body weight, lean-back load, and floor friction simultaneously. The algorithm cuts them to mm-precise length, but cut slowly and carefully.

Curved or straight back?+

Straight is easier; curved is more comfortable. First chair: straight. Second chair: gentle curve (R200–R300 radius).

Do I have to upholster the seat?+

No. Finish the chair and send it to an upholsterer ($10–17 per chair) — cheaper and faster than doing it yourself.

Back-rail spacing?+

Ergonomic guidance: 5–7 rails, 5–8 cm spacing. Sparser = poor back support, denser = visually heavy. The template auto-spaces evenly based on rail count.

How long for 6 chairs?+

First one takes 2–3 working days (you're learning). Batch the next 5 — practiced hands can do one a day. Full set runs 2–3 weeks.
