HINGE SIZE & QUANTITY GUIDE

How many hinges do I need?
Most doors require either 2 or 3 hinges depending on the door’s size, weight, and use. Smaller or lighter doors may only need 2 hinges, while standard full-height interior doors commonly use 3 hinges for better support and long-term alignment.

How do I check hinge weight capacity?
Check the total weight of your door and divide it by the number of hinges you plan to use. The estimated weight per hinge should stay within the hinge’s stated weight capacity. For example, a heavier 150 kg door may require 3 × 5 in hinges or 4 × 4 in hinges, depending on the door, frame, and installation conditions.

Why use 3 hinges?
Three hinges help distribute the door’s weight more evenly across the frame, reduce strain on each hinge, and help prevent sagging over time.

What should I check before ordering?
Check your door weight, door height, frame construction, hinge weight capacity, and existing hinge cutouts. For replacement projects, match the existing hinge size and quantity where possible, or follow your installer’s recommendation.

WHY CHOOSE SOLID BRASS

Solid brass offers a heavier, more substantial feel than many lower-cost alternatives, giving the hinge a more refined and premium character in daily use.

It is valued for its durability, clean machining, and timeless appearance, making it a strong choice for interior hardware that is meant to feel as good as it looks.

Unlike lighter hollow or lower-grade alternatives, solid brass provides:

  • noticeable weight and presence
  • clean, precise detailing
  • strong long-term durability
  • a more premium architectural feel
INSTALLATION GUIDE

Door Hinge Installation Guide

Before You Begin

Door hinges are installed along the edge of the door and secured to the matching door frame or jamb. The exact installation method depends on the hinge style, door type, and frame construction.

For best results, confirm your hinge size, door thickness, swing direction, and required placement before cutting or drilling.

Tools You May Need
  • Phillips or flathead screwdriver
  • Drill and drill bits
  • Chisel
  • Hammer or mallet
  • Tape measure
  • Pencil
  • Level or square
  • Screws
  • Router, if preferred for mortising or concealed hinge installation

A. Mortise Hinge Installation

Step 1: Mark the Hinge Positions

Measure and mark the hinge locations on the edge of the door. A common placement is:

  • Top hinge: Approximately 5–7" from the top of the door
  • Bottom hinge: Approximately 10–12" from the bottom of the door
  • Middle hinge, if used: Centered between the top and bottom hinges

Repeat the same layout on the door frame so the hinge leaves align correctly.

Step 2: Trace and Cut the Mortise

Place the hinge leaf against the marked area and trace around it. Using a chisel or router, cut a shallow recess into the door edge and frame so the hinge leaf sits flush with the surface.

Take care not to cut too deeply, as this can affect door alignment and closing.

Step 3: Drill Pilot Holes

Set the hinge into the mortise and mark the screw positions. Remove the hinge, then drill pilot holes to help prevent splitting and make screw installation easier.

Step 4: Secure the Hinges

Attach one hinge leaf to the door edge using the supplied screws. Once the hinges are fixed to the door, position the door in the frame and secure the opposite hinge leaves to the jamb.

Step 5: Check the Door Movement

Open and close the door slowly to confirm smooth movement. If the door rubs, binds, or does not sit evenly, adjust the screws or hinge position as needed.

B. Concealed Hinge Installation

Step 1: Mark the Recess Locations

Mark the hinge positions on both the door edge and the frame. Concealed hinges require deeper recesses than standard mortise hinges, so measure carefully before cutting.

Step 2: Cut the Hinge Recesses

Using a router or chisel, create recesses deep enough to fit the concealed hinge body. The hinge should sit securely and flush once installed.

Step 3: Position and Drill

Place the hinge into the recess and check alignment. Mark the screw holes, then drill pilot holes for the fasteners.

Step 4: Fasten the Hinges

Secure the concealed hinge into the door and frame using the supplied screws. Make sure each hinge is fully seated before tightening.

Step 5: Adjust the Alignment

Many concealed hinges include adjustment screws for fine-tuning the door position. Use these to adjust the door vertically, horizontally, or in depth until the reveal is even and the door swings properly.

Step 6: Test the Operation

Open and close the door fully to make sure it moves smoothly, closes correctly, and does not rub against the frame.

Installation Tips

  • Measure and mark all hinge positions before drilling or cutting.
  • A properly cut mortise allows the hinge to sit flush and helps the door close correctly.
  • Use a level or square to keep the hinges aligned.
  • For heavier doors, three hinges are generally recommended.
  • Avoid overtightening screws, as this may strip the holes or affect alignment.
  • Check and tighten screws periodically to maintain smooth operation.
  • If installing into a new or custom door, professional installation is recommended.
