How to Choose Cabinet Hinges: A Complete Buyer's Guide
A practical guide to hinge types, 35 mm cup specifications, opening angles, overlay styles, soft-close testing, materials, finishes and OEM sourcing — written by a factory that manufactures them.
Start with the hinge type
Furniture hinges fall into two broad families: visible hinges (butt hinges, decorative hinges) and concealed hinges. Concealed hinges — the European cup hinge — dominate modern kitchens and wardrobes because the mechanism is hidden when the door is closed, the door is fully adjustable, and production can be automated. Within concealed hinges you choose between screw-on and clip-on mounting: screw-on hinges are fixed with two screws on the hinge arm and are traditional and low-cost; clip-on hinges click onto a mounting plate, which speeds up production-line assembly and makes doors easy to remove for transport or service. Soft-close versions add a hydraulic damper that slows the door in the last few millimeters. For frameless doors, pivot hinges are a compact alternative. If your project is glass doors or aluminum profiles, you will need specialty hinges rather than standard cup hinges.
The five specifications that matter
1) Cup diameter — 35 mm is the European standard and fits most drilling patterns; other diameters exist for special doors. 2) Drilling distance — the distance from the cup edge to the drill holes, typically 3–7 mm (48 mm and 52 mm hole distances are the most common cup patterns). 3) Opening angle — 90° for standard doors, 105°–110° for most kitchen cabinets, 135°–165° for wide-opening or specialized layouts. 4) Overlay style — full overlay (door covers the cabinet side), half overlay (paired doors share a partition) or inset (door sits inside the frame). 5) Mounting — screw-on or clip-on. If any of these is wrong, the door will not align or will not open correctly. Send these five values with your inquiry and you will get an accurate quotation the first time.
Soft-close: what to test, not just what to buy
A soft-close hinge is only as reliable as its damper. Ask your supplier three questions: What is the rated cycle life? (80,000 open/close cycles is the quality benchmark for kitchen hinges.) Is the damper sealed? (A sealed, factory-calibrated damper needs no on-cabinet adjustment and lasts longer.) What salt spray test is applied to the finish? (48 hours minimum for nickel-plated steel in humid kitchens.) Our hinges are tested to exactly these standards, and test reports are available on request. For stainless steel models, the same 48-hour salt spray program confirms corrosion resistance for coastal installations.
Materials, finishes and where they belong
Cold-rolled steel is the standard hinge body for kitchens and furniture: strong, formable and inexpensive, normally plated with nickel or chrome for corrosion resistance. Stainless steel 304 is specified for humid, coastal or sanitary environments; 316 adds molybdenum for marine and high-chloride conditions and can be mirror-polished. Finishes matter for both appearance and durability: nickel (classic), chrome (bright), bronze and black (design-led kitchens), satin (contemporary). If your market is coastal, humidity-heavy or outdoors, choose stainless rather than plated steel — and ask for the salt spray report rather than a verbal guarantee.
Sourcing hinges for OEM: the checklist
When sourcing from a factory, send: (1) your drawing, sample or reference photo; (2) the five specifications above; (3) target quantity and MOQ; (4) finish and packaging requirements; (5) destination port for logistics. A capable OEM supplier will confirm feasibility, tooling and price within 24 hours, ship samples in about 7 days, and run production in 15–20 days after approval. Our standard MOQ is 100 pieces for stock models and 5,000 pieces for custom drilling, logos or packaging. Ask for the salt spray report, cycle test data and material certificates — a factory that tests publishes the numbers.
Frequently Asked Questions
35 mm is the European standard; 45 mm and 52 mm hole distances are the most common drilling patterns.
