Custom dining chair dimensions need to work with the table, the people using it and the space around it. Upholstery also changes the feel and care routine. This guide shows what to measure and which material questions to ask before requesting a dimensioned drawing and a sample from OKKHM.
Measure the chair together with the table
Start with your actual table: record the floor-to-underside clearance at the apron or frame, the location of table legs, and the usable distance between legs. Then measure the room’s circulation space when a chair is pulled out. A chair can fit neatly under a tabletop yet still be awkward to sit in if an apron, armrest or leg blocks movement.
| Dimension to confirm | Why it matters | How to specify it |
|---|---|---|
| Overall chair width, depth and height | Controls spacing between diners and storage footprint. | Ask for maximum outside dimensions, including arms and the widest part of the base. |
| Seat height from floor | Determines the seated position at your specific table. | Ask whether the number is measured with or without cushion compression. |
| Seat width and usable depth | Determines the actual sitting area, which can differ from overall size. | Request a diagram from the front and side. |
| Armrest height and clearance | Determines whether an armed chair slides beneath the table. | Compare to the table’s lowest underside point, not just tabletop height. |
| Leg or frame footprint | Can interfere with table legs and affect floor protection. | Request base width/depth, contact points and floor-glide details. |
Do not treat a size selector alone as a production drawing. Several OKKHM dining chair listings show the same preset sizes; ask for a model-specific drawing with width, depth, height, seat and arm measurements confirmed in centimeters before paying for a custom configuration.

Choose a material for the way the chair will be used
OKKHM lists a velvet cantilever model and a separate Nordic PU leather model. These are different starting designs; do not assume every upholstery or frame option is interchangeable. Ask for current swatches and a written bill of materials for the chosen chair.
| Material direction | What to inspect | Question to send OKKHM |
|---|---|---|
| Velvet upholstery | Color and pile direction in daylight, hand feel and cleaning behavior. | What is the exact fabric code, composition and care instruction for this chair? |
| PU leather upholstery | Surface texture, color consistency, edge treatment and care. | Which surfaces use PU and what is the current material specification? |
| Other fabric or genuine leather, if offered | Swatch and the stated material type; leather and PU must be labeled separately. | Is this available on the selected frame, and what changes in price and lead time? |
| Metal, wood or other frame | Joint details, finish, floor contact and sample stability. | What frame material and finish will be supplied for this configuration? |

Home, restaurant or project purchase?
For a home dining room, check table clearance, comfort, color and the cleaning instructions for everyday spills. For a café, restaurant or larger furnishing project, also request written information on the exact fabric’s abrasion performance, relevant fire requirements for the destination, frame construction and replacement-part policy. Required standards vary by market and project; do not assume a product photograph or a generic “commercial” label proves compliance.
When comparing quotations, keep the same chair design, material code, dimensions, quantity and packing format in each request. A cheaper quote with a different seat material or frame is not equivalent. Confirm whether chairs ship assembled or knocked down and check carton dimensions against the delivery route.
Brief a custom order from one piece
OKKHM advertises MOQ 1 for custom furniture enquiries. Send one chair product link or reference photo, quantity, your table’s underside clearance and leg spacing, preferred chair outside/seat/arm dimensions, upholstery and frame choice, destination and target date. Request a drawing, material swatch, sample terms, itemized price, packing details and lead time for that exact configuration. A one-piece enquiry does not mean every custom option has the same price or timing.
Next step: Use the custom furniture RFQ template to organize your brief. For other seating dimensions and material decisions, see the custom sofa size and fabric guide.
Pair the chosen chair with a dimensioned table plan. Our dining table size and seating layout guide shows transparent 4-, 6- and 8-seat examples; replace its illustrative chair width with the actual model measurement.
Frequently asked questions
What dining chair dimensions should I send?
Send overall width/depth/height, preferred seat height and usable depth, armrest height if any, and your table’s underside and between-leg clearances. Ask for a model-specific drawing in centimeters.
Is PU leather the same as genuine leather?
No. Request the exact upholstery name and composition in writing. A product photo alone cannot confirm the material supplied.
Can I order just one custom dining chair?
OKKHM advertises MOQ 1 for custom furniture enquiries. Ask which material, size and finish changes are feasible for the chosen model, and obtain a written quote and timing.
