Have you ever walked past a door in your home and noticed it just doesn't look right? Maybe it's dragging on the carpet, scraping the frame, or simply sitting unevenly in the jamb. A misaligned door isn't just an aesthetic annoyance; it can lead to damaged floors, ruined hardware, and a door that refuses to close properly.
In modern homes, many of these doors are mounted on what are known as hidden hinges—also called concealed or European hinges. These hinges are popular for a reason. They offer a sleek, clean look because they are completely invisible when the door is closed. However, their sophisticated design can make them seem intimidating to adjust compared to traditional butt hinges.
The good news is that adjusting these hinges is often easier than it looks. You don't need to be a professional carpenter or have a workshop full of tools. With a simple screwdriver and a little patience, you can get your doors hanging perfectly straight again. This guide will walk you through the process of adjusting the vertical height of your door using hidden hinges, ensuring smooth operation and a polished look for your home.
Before you start turning screws, it is helpful to understand what you are working with. Hidden hinges are marvels of modern hardware engineering. Unlike traditional hinges that have a single pivot point (the pin), hidden hinges typically have multiple pivot points and adjustment screws. This design allows for "3-way" or "3D" adjustability:
Vertical: Moving the door up and down.
Horizontal: Moving the door left and right.
Depth: Moving the door in and out (closer to or further from the frame).
This adjustability is the primary advantage of hidden hinges. If a house settles or humidity swells the wood, you can simply tweak the hinge settings rather than re-hanging the entire door.
Not all hidden hinges are identical. While the principles are similar, the specific location of the adjustment screws can vary by brand (such as Blum, Salice, or SOSS).
Open the door fully: This gives you clear access to the hinge mechanism.
Look for screws: You will typically see mounting screws (which hold the hinge to the wood) and adjustment screws (which move the hinge parts).
Check for caps: Some high-end architectural hidden hinges have cover plates that hide the screws. You may need to pop these off gently with a flathead screwdriver or your fingernail.

You likely already have everything you need in your junk drawer.
Phillips Head Screwdriver: Most hidden hinges use a standard #2 Phillips screw.
Hex Key (Allen Wrench): Some heavy-duty or architectural hinges use hex screws for adjustments.
Tape Measure or Level: Useful for checking your progress.
Wood Shims (Optional): Helpful for supporting the door weight during adjustment.
A Helper (Optional but Recommended): While you can do this alone, having someone to hold the door steady makes the process much smoother.

Vertical adjustment fixes issues where the door is dragging on the floor or hitting the top of the door frame. Here is how to do it.
Open your door and examine the hinges. Most doors will have two, three, or even four hinges depending on their weight. You need to adjust all of them to move the door effectively.
The vertical adjustment mechanism is usually controlled by two specific screws on each hinge:
The Locking/Clamping Screws: These screws hold the hinge plate in place. They are often located in oval-shaped slots that allow for up-and-down movement.
The Adjustment Cam or Screw: Some hinges have a dedicated gear or cam screw that, when turned, physically lifts or lowers the door.
If you are unsure which screw does what, consult the manufacturer's manual or look for small arrows stamped into the metal of the hinge indicating direction.
This is the most crucial step that beginners often skip. You are about to loosen the screws that hold the door up. If you loosen them all at once without support, the door could drop suddenly, damaging the screws or the hinge itself.
If you have a helper, ask them to lift the handle slightly to take the weight off the hinges. If you are working solo, slide a wood shim or a specialized air wedge under the bottom corner of the door. This supports the weight so the hinges can move freely.
On standard European-style concealed hinges (common on cabinets and some lightweight doors), the vertical adjustment is done on the mounting plate attached to the cabinet or frame side.
Loosen the two mounting screws on the top and bottom of the hinge baseplate slightly. Do not remove them. Just turn them counter-clockwise about a half-turn to a full turn. The hinge needs to be loose enough to slide but tight enough not to fall off.
Repeat this for every hinge on the door. It is essential to do this for all hinges simultaneously so they don't fight against each other.

Now comes the actual adjustment.
Manual Adjustment: If your hinges rely on oval slots, you can now manually push the door up or down to the desired height. This is where the shim or your helper comes in handy to hold it at the perfect level.
Cam/Gear Adjustment: If your hinges have a dedicated vertical adjustment screw (often a spiral cam), turning this screw will move the hinge plate up or down with precision. Turn the screw clockwise to raise the door and counter-clockwise to lower it.
Make sure you adjust all hinges equally. If you raise the top hinge but not the bottom one, you will put uneven stress on the hardware, which can cause squeaking or premature failure.
Once the door looks level and the gaps at the top and bottom are even:
Tighten the screws: Go back to every hinge and firmly tighten the locking screws you loosened in Step 3.
Remove support: Take out the shims or have your helper let go.
Test the swing: Open and close the door several times. Does it close smoothly? is the gap at the top consistent? Does it clear the floor covering?
If the door still drags or looks crooked, you may need to repeat the process. It often takes two or three small tweaks to get it perfectly aligned.
Sometimes, a simple height adjustment isn't enough. If you are still facing issues, check these factors.
If the door sags immediately after you adjust it, the screws might be stripped, or the wood behind the hinge might be compromised.
Fix: You can try using longer screws to bite into fresh wood deeper in the frame. Alternatively, remove the screw, fill the hole with wood glue and toothpicks (or a dowel), let it dry, and re-drill the pilot hole.

If the height is correct but the door still rubs against the side of the frame, you need to adjust the horizontal or depth settings, not the height.
Horizontal Adjustment: Look for a screw on the hinge arm closest to the door. Turning this moves the door closer to or further from the hinge side of the frame.
Depth Adjustment: This is usually a screw at the very back of the hinge arm. Adjusting this moves the door face in or out relative to the frame face.

Hidden hinges are complex mechanisms with moving parts. Over time, metal fatigue can cause internal springs or pivot arms to snap. If a hinge feels loose despite all screws being tight, or if it makes a popping sound, it likely needs to be replaced.
Taking twenty minutes to adjust your hidden hinges does more than stop a squeak. It prolongs the life of your entire door system. When a door drags, it puts lateral torque on the hinges that they weren't designed to handle. This can warp the hinge plates or even crack the door frame over time.
Regularly checking your doors—perhaps once a year when the seasons change—ensures everything stays tight and aligned. It prevents minor annoyances from turning into major repairs.
Hidden hinges are a fantastic element of modern interior design, offering clean lines and sophisticated functionality. While they might seem complex at first glance, they are designed with user-friendliness in mind. The ability to fine-tune the door's position in three dimensions means you can always achieve that perfect, satisfying "click" when the door closes.
Don't let a dragging door scratch up your floors any longer. Grab your screwdriver, follow these steps, and get your home's hardware back in top shape.
