Buying Guide · April 2026
You've picked your hinges. Now you need to know how many to order. Get it wrong and you're either paying for a second shipment or left with a pile of extras. This guide gives you the simple rule, the exceptions, and everything you need to count your exact order.
The simple rule
For the vast majority of standard kitchen and bathroom cabinet doors, the answer is 2 hinges per door. This covers doors up to 40 inches tall made from standard materials like MDF, plywood, or hollow-core wood.
Taller doors, heavier doors, or doors with special features need a third hinge. The section below explains exactly when to add one.
Quick answer
Under 40" tall, standard material → 2 hinges. Over 40" tall, or heavy/solid wood/glass panel → 3 hinges. Over 60" tall → 4 hinges. When in doubt, add one more — an extra hinge costs $9 and prevents a sagging door.
The full guide: when 2 hinges isn't enough
Door height
Height is the primary factor. As a door gets taller, the leverage force on the top hinge increases — the longer the door, the harder that hinge has to work every time the door is opened and closed. A third hinge in the middle distributes this load.
| Door height | Standard material | Heavy material |
|---|---|---|
| Under 30" | 2 hinges | 2 hinges |
| 30"–40" | 2 hinges | 3 hinges |
| 40"–60" | 3 hinges | 3–4 hinges |
| Over 60" | 4 hinges | 4+ hinges |
Door weight
Weight adds load to every hinge, especially over time. These door types consistently need an extra hinge regardless of height:
- Solid wood doors — significantly heavier than MDF or hollow core. Add a hinge if the door is over 30" tall.
- Glass panel inserts — even a partial glass panel adds 3–5 lbs. Always use 3 hinges on any door with glass.
- Thick boards (over 3/4") — thicker stock is denser and heavier. Treat like solid wood.
- Painted MDF with heavy primer — multiple coats of paint and primer add meaningful weight on large doors.
Door width
Width matters less than height and weight for hinge count, but very wide doors (over 24") create more leverage when open. For wide doors on pantries or wardrobe-style cabinets, err toward adding a third hinge.
When in doubt
A third hinge costs about $9. A sagging door that pulls its mounting screws out of the frame costs significantly more to fix. If you're on the borderline, add the hinge.
Where to position the third hinge
When adding a third hinge, placement matters. The goal is to distribute load evenly along the door's height:
- Top hinge: 2"–3" from the top of the door
- Bottom hinge: 2"–3" from the bottom of the door
- Middle hinge: exactly halfway between top and bottom hinges — not halfway along the total door height
For a 48" door with top hinge at 3" and bottom hinge at 45", the middle hinge goes at 24" — the midpoint of the 42" span between the two outer hinges.
How to count your total order
Walk through your kitchen or bathroom and count every door. A typical American kitchen breaks down like this:
| Cabinet type | Typical doors | Hinges each | Subtotal |
|---|---|---|---|
| Upper cabinets (standard) | 8 | 2 | 16 |
| Lower cabinets (standard) | 8 | 2 | 16 |
| Pantry / tall cabinet | 2 | 3 | 6 |
| Total | 18 doors | — | 38 hinges |
38 hinges means ordering 2 × 20-packs (40 hinges, 2 spare) or 4 × 10-packs (40 hinges, 2 spare). Having 2–4 spare hinges is sensible — if you damage one during installation or one develops a fault under warranty, you have a replacement on hand without waiting for a new order.
Frequently asked questions
Do I need to use the same number of hinges on every door?
No. Each door is independent. It's perfectly normal to use 2 hinges on standard upper cabinet doors and 3 on a taller pantry door in the same kitchen. The hinges look identical from the outside — only the count differs.
Can I add a third hinge later if the door starts to sag?
Yes. You'll need to drill a new 35mm cup hole at the midpoint of the door, which requires a Forstner bit. It's a straightforward DIY job. That said, it's much easier to install all the hinges at once during the initial fit-out — adding one later means removing the door again.
Does the number of hinges affect soft close performance?
Slightly. More hinges means more dampers engaged on each close, which can make the action feel marginally slower. For most doors this is imperceptible. If you're installing 3 soft close hinges on a lightweight door and the action feels too slow, you can adjust the damper tension on each hinge individually.
Should I order a few extra as spares?
Yes — 2 to 4 spares is a sensible buffer. Hinges can be damaged during installation (stripped screw holes, misaligned bore), and having a matching spare on hand saves waiting for a reorder. Since Furniware sells in packs of 10, 20, and 50, it's worth rounding up to the next pack size rather than ordering the exact count.
I have a mix of door heights. Should I use the calculator multiple times?
Yes — run the calculator once for each door type (e.g. once for 8 standard upper doors, once for 2 pantry doors), then add the totals together before choosing your pack size. This gives you the most accurate order count.
