How Do You Build a Frame for Wardrobe Doors?

You build a frame for wardrobe doors by fixing a timber subframe into the opening: a head plate at the top, a sole plate or floor batten at the bottom, and vertical stiles at each side, all squared up and packed level before the doors are hung. The frame carries the hinges or the sliding track, so its accuracy matters more than any other part of the job. Get it square and plumb and the doors will close cleanly for years. Get it wrong by a few millimetres and no amount of hinge adjustment will hide it.

This job is well within reach for anyone comfortable with a drill, a saw and a spirit level. The skill lies in dealing with the out of square openings that are normal in British houses, especially in older properties and converted loft spaces.

Choose the Frame Type Before You Cut Anything

There are two broad approaches. A face frame sits on the front of the opening and the doors close against it, which suits alcoves with rough or uneven reveals because the frame hides the imperfections. A recessed frame sits inside the opening with the doors flush or inset, which looks neater but demands a more accurate opening.

For hinged doors you need solid vertical stiles with enough thickness to take hinge screws, so 38mm by 63mm planed softwood or thicker is sensible. For sliding doors the top track carries most of the weight, which means a strong, dead level head plate and much less demand on the sides.

Decide the door arrangement now too. Two doors on a 1200mm opening behave differently from three on the same span, and the stile positions depend on that choice. If you are considering sliding panels, look at how our sliding wardrobes UK sale designs divide their openings, because the same proportions work well in a self built frame.

Survey the Opening Properly

Measure the width at floor level, at mid height and near the ceiling. Then measure the height at both sides and in the centre. Write everything down. Differences of 10mm to 20mm across a domestic alcove are entirely normal.

Check the walls for plumb with a long spirit level or a laser. Check the floor for level across the full width. Check the ceiling too, since older ceilings often dip in the middle.

Use the smallest measurements as your working dimensions, because the frame must fit the tightest point. The surplus at the wider points gets taken up with packers behind the frame and covered later with trim or filler.

Before drilling, locate services. Cables run vertically above and below sockets and switches, and horizontally near ceiling level in some properties. Use a detector and take your time here.

Building and Fitting the Frame

Cut the head plate and sole plate to your working width, and the stiles to the working height minus the combined thickness of those two pieces. Assemble the frame flat on the floor if space allows, screwing through the head and sole plates into the ends of the stiles. Pilot drill every hole to stop the softwood splitting.

Check the frame for square by measuring both diagonals. When the two measurements match, the frame is square. Fix a temporary diagonal brace across the back to hold it while you lift it into place.

Stand the frame in the opening and shim it with packers until the stiles are plumb and the head is level. Do not force the frame to follow a leaning wall: it must be square in itself, with the discrepancy taken up behind it. Fix through the stiles into the wall with frame fixings suited to the substrate, using plasterboard anchors only if you cannot reach a stud, and screw the sole plate down into the floor joists where possible.

Once fixed, recheck the diagonals and the plumb of each stile. Remove the brace only when you are satisfied. Any error you accept now becomes a permanent gap along a door edge.

Allowing the Right Clearances

Doors need room to move. For hinged doors, allow around 3mm at the top, 3mm at the sides and 5mm to 8mm at the bottom, with a similar gap between paired doors. Concealed hinges tolerate a little more, since they offer three way adjustment.

For sliding doors the geometry is different. The top track needs to be dead level along its full length, and the bottom track or floor guide must sit directly beneath it. Sliding doors also need enough depth in the frame for two panels to pass each other, usually around 100mm from the front face to the back of the rear panel, so check the specification of your track before finalising the frame depth.

Mark the hinge positions on the stile before hanging anything. Two hinges suit doors up to roughly 1200mm tall, three up to about 1800mm, and four beyond that or on any heavy or mirrored door.

Cladding, Trim and Finishing

Once the frame is fixed, clad it. Slim MDF or plywood facings screwed or pinned to the stiles and head give a clean paintable surface and cover the packers behind. Set the facing back or forward depending on whether you want the doors inset or overlaid.

Fill the joint between the frame and the wall with flexible decorators caulk rather than rigid filler, so seasonal movement does not open a crack. Fill screw holes with two part filler, sand flush and prime everything before the final coats.

Paint the frame before hanging the doors. Painting around fitted doors in a tight bedroom is slow and the result is rarely as clean. Choose an eggshell or satin finish for durability on a surface that gets brushed against daily.

Think about how the finished frame relates to the rest of the room. Matching the frame colour to the door architrave makes it read as original joinery, while matching it to the walls makes the whole run recede. If the bedroom already contains pale timber pieces such as a modern wooden chest of drawers UK, a warm off white on the frame usually sits more comfortably than a cool brilliant white.

Fitting the Interior Behind the Frame

A frame is only worth building if the space behind it works. Plan the interior before you close it in, because access afterwards is limited.

A single full width hanging rail at around 1750mm from the floor suits long coats and dresses. Double hanging, with rails at roughly 1000mm and 2000mm, doubles capacity for shirts and folded trousers. Leave at least 550mm of internal depth for a standard front to back rail, or fit end to end rails in a shallower space.

Add shelving above the rail for boxes and bedding, and consider a drawer bank or basket at the base. Where the frame encloses a deep or awkward recess, a freestanding unit slotted inside can be easier than building fitted joinery, and our modern shelving units and storage UK options work well for that.

If you would rather avoid building at all, a well chosen freestanding piece often solves the same problem. You can compare fitted style and freestanding designs across our bedroom range at Furniture in Fashion.

Where Frames Usually Go Wrong

The most frequent mistake is scribing the frame to a leaning wall so that it is out of square. The frame must be square in itself. Everything else is packed and covered.

The second is a sagging head plate on a wide opening. Anything over about 1500mm needs either a deeper section or a fixing back into the ceiling joists, otherwise the middle drops and sliding doors bind.

The third is ignoring the floor. Carpet and underlay add 10mm to 20mm of height, and fitting a frame to bare boards before the carpet goes down leaves no bottom clearance. Decide the final floor level first.

Finally, do not underestimate door weight. Mirrored and solid core doors are heavy, and a lightweight frame with plasterboard fixings will pull loose within months. Fix into studs or use proper heavy duty anchors.

Frequently Asked Questions

What timber size should I use for a wardrobe door frame?
Planed softwood of 38mm by 63mm suits most openings, and 47mm by 75mm is better for wide spans or heavy doors. The stiles need enough thickness to hold hinge screws securely.

How much clearance do wardrobe doors need in the frame?
Allow roughly 3mm at the top and sides, and 5mm to 8mm at the bottom for hinged doors. Sliding doors follow the track manufacturer’s figures, which usually require a level head and around 100mm of depth.

Can I build a frame if my walls are not plumb?
Yes, and this is the normal situation. Build the frame square, then pack behind it so the frame stays square while the gap to the wall varies. Cover the gap with trim or caulk.

Do I need to fix the frame into the ceiling?
For openings wider than about 1500mm, or for sliding doors of any width, fixing the head plate into the ceiling joists is strongly advisable to prevent sagging.

Should I paint the frame before or after hanging the doors?
Before. Painting a fitted frame around hung doors is slower and the finish is rarely as clean, particularly in the corners and along the closing edges.
