Door frames: Types, Dimensions, Materials, and Installation Explained

A door frame, also commonly referred to as a door jamb, connects the door leaf to the wall. It supports the door hinges, houses the striking plate, and defines the appearance of the entire door. But which frame is right for which wall, how do you measure it correctly, and what are the differences between a wrap-around frame, a block frame, and a corner frame? This guide explains the most important types of frames, materials, dimensions, and installation steps.

What are door frames?

Door frames are also colloquially referred to as door frames. A door frame is the immovable part of the door, which frames the wall in the area of the door opening, as well as completely or partially covers the sides of the door reveal. By reveal is meant the inner surface of the wall in the area of the opening. In very simplified terms, the door frame forms a frame around the open area in the wall where the door is inserted.

Thus, a frame is not only the foundation of a good door - it also contributes to the aesthetics of the room. The design of the door leaf and the door frame should therefore be visually coordinated.


What is a door frame made of?

Frames are usually made of wood or wood-based materials. For fire protection or security doors, frames can also be made of steel or aluminum. As a rule, the frame is made of the same material as the door leaf, but it can also be different: Glass doors, for example, usually have a frame made of metal or wood.Frames are usually made of wood or wood-based materials.

What is the structure of a door frame?

A classic door frame consists of several components:

  • Frame sides: The side elements of the frame accommodate the door hinges and striking plate.
  • Frame crosspiece: The upper horizontal element connects the two side sections.
  • Rebate: The closed door leaf rests against this stepped area.
  • Seal: A perimeter seal reduces closing noise and minimizes drafts.
  • Casing: It covers the transition between the frame and the wall.
  • Decorative trim: On the opposite side, it covers the door opening and ensures a clean wall connection.

Depending on the frame type, the construction and terminology may vary. Block, corner, and Steel frames are constructed differently from classic surround frames.


What is the technical purpose of a door frame?

In the case of hinged doors, the door frame serves to accommodate the door hinges. These are connected to the door leaf and attached to what is known as the frame jamb. The hinge mechanism allows the door leaf to pivot, enabling the door to open and close. In addition, the door frame supports the weight of the door leaf via the door hinges.

For single-leaf doors, the striking plate is anchored in the opposite side of the door frame. These are the openings into which the latchbolt or deadbolt engages when the door is closed.

Furthermore, there are door frame models with a circumferential rebate—a stepped recess. The door leaf fits precisely into this rebate, ensuring that the door closes particularly tightly. In some cases, plastic gaskets are even installed in the door frame rebate. These dampen the sound of the door slamming, compensate for minor tolerances, and reduce drafts as well as the transmission of noise. The effectiveness of the seal depends on the entire door assembly, consisting of the frame, door leaves, floor gap, and, if applicable, a floor gasket.


What are the types of door frames?

Whether perimeter frame, corner frame, through frame, block frame or frame frame - all these door frames are mainly used for doors in masonry or concrete walls. For lightweight walls in drywall construction, special stud frames are used.  We explain the different types of door frames.

 

Surrounding frame

The perimeter frame is most often installed in German buildings. It covers the entire door reveal, forming a frame around the door opening on both sides. On the side where no door is installed, it is a decorative frame: this frame has no technical functional use, but only provides a coherent image. After all, a doorway with a half-sided frame would look strange. In addition, the perimeter frame protects the corners of the wall. It is suitable for both masonry and stud walls.

 

Block frame

A block frame is installed within the door opening or in the reveal. It does not enclose the wall with side panels on both sides and therefore has a more minimalist appearance than a traditional surrounding frame. Depending on the design, it sits flush with the wall surface, centered in the reveal, or at a specific position within the opening.

Block frames are frequently used in modern residential and office buildings. Since there is no trim or the trim is very narrow, the wall opening and connections must be executed with particular precision.

A special type of block frame is the stick frame. It is without a face frame and does not cover the entire door opening. However, it is installed in the center of the reveal and does not span the full width of the reveal.

Frame for blinds

Als Gegenstück zur Blockzarge greift die Blendrahmenzarge überhaupt nicht in die Laibung ein. Ganz im Gegenteil: Sie verblendet nur die Wandöffnung und ist daher vor ihr befestigt. Vereinfacht gesagt: Die Blendrahmenzarge deckt die Wandöffnung nur außen ab. Meist wird sie in der Wand verdübelt. Die Blendrahmenzarge eignet sich daher besonders für kleine Maueröffnungen, da der Blendrahmen bei breiten und schmalen Wandstärke gleichermaßen montiert werden kann.

 

Passageway frame

The through frame takes aesthetic utility to the extreme, as it is a purely ornamental frame. Passage frames have no technical necessity. Although they protect the wall from mechanical damage - but they are mounted only on wall openings in which no door is inserted. Thus, this door frame should only attractively disguise the opening or passage.

 

Corner frame

The corner frame, unlike the through frame, is a purely functional frame. It is mounted directly on the corner of the wall. It is used where the wall reveal is too small or too deep for a perimeter frame. Moreover, the corner frame does not interfere much with the reveal, as it covers the wall opening only on one side of the door leaf. This door frame is used where appearance must give way to functionality, e.g. in storage rooms or in the basement.

 


How much do room doors with door frames cost?

The price of a door frame varies depending on various factors: material of the frame, material of the door leaf, type of frame, filling of the door leaf, type of door, type of surface seal, additional design elements, dimensions, etc. You can find more information on the different types of doors in our articles on"Interior doors" and"Door leaves".

Do sliding doors need a door frame?

A sliding door does not necessarily require a traditional door frame. For a sliding door that runs in front of the wall, the wall opening can be plastered, covered with a passage frame, or combined with an existing frame.

Wall-integrated sliding doors are also available with a visible frame or as a largely frameless solution. Which option is suitable depends on the wall construction, the desired design, and how it coordinates with other doors in the room.


Measure the door frame correctly: Wall thickness, rebate dimension & passage width

Three dimensions are decisive for the right frame - and always in the finished state (including plaster, planking, floor structure):

1) Wall thickness

Measure the finished wall—including plaster, tile, or wall paneling—at several points. The frame depth must match the greatest measured wall thickness or fall within the frame's adjustment range.

2) Rebate dimension

  • The rebate dimension is the internal dimension of the frame at the rebate plane - it determines whether the door leaf will fit.
  • Check the manufacturer's specifications for air gaps (closing and hinge side) and seals if necessary.

3) Clearance dimensions

Measure the finished wall—including plaster, tile, or wall paneling—at several points. The frame depth must match the greatest wall thickness measured or fall within the frame's adjustment range.

3 Tips for Measuring a Door Frame

Width of the wall opening

Measure the opening at the top, in the middle, and at the bottom. The smallest measurement is usually the one that counts. Observe the installation and assembly tolerances specified by the manufacturer.

Height of the wall opening

Measure from the top edge of the finished floor to the bottom edge of the door lintel. If the flooring has not yet been installed, account for the subfloor, underlayment, and the final flooring.

Door Opening Direction

Determine whether the door should be hinged on the left (DIN left) or right (DIN right). The decisive factor is the side on which the door hinges are visible when the door is closed.

Measurement checklist

  • Measure the carcass opening at the top/middle/bottom, check diagonals (squareness).
  • Document any unevenness in the reveal; plan compensation if necessary.
  • Observe the manufacturer's dimensional tolerances; plan for installation wedges/clamps.
  • When renovating: Inspect the old frame (damage, bonding, plastering).

Typical orientation values

  • Wall thickness 100-115 mm → often drywall construction; cladding width approx. 60-70 mm.
  • Wall thickness 120-145 mm → standard masonry; cladding width approx. 70-80 mm.
  • Wall thickness 150-180 mm → thicker walls/old building; cladding width approx. 80-100 mm.

Tip: Note down wall thickness + floor structure + desired stop direction (DIN left/right). This speeds up consultation and ordering.


Installing the door frame: Step-by-step guide

Many traditional interior door frames made of wood-based materials can be installed by yourself with some hands-on experience. It is crucial to ensure that the frame is assembled at exact right angles, aligned vertically and horizontally, and that the manufacturer’s instructions are followed.

The specific fastening method varies depending on the frame type. While some perimeter frames are secured with approved mounting foam, other systems require mechanical screw fastening. Fire, smoke, soundproof, and security doors must only be installed in accordance with their certification and Installation instructions.

For irregular wall openings, heavy door leaves, or functional door elements, installation by a specialized contractor is recommended.

Safety and quality instructions

  • Observe moisture/fire protection requirements (suitable frame/seal).
  • Observetemperature/humidity when foaming; too much foam will warp the frame.
  • Document gap dimensions, plan for readjustment after 24 hours.

Door frame costs: examples & price factors

What should you expect? Prices vary according to material, surface, frame type and special dimensions.

Orienting examples (without assembly):

  • Surround frame, wood-based material/CPL (standard): approx. 120-250 €

Door frame: Wood, Steel, or Aluminium? A Comparison of Materials

Wood/wood-based material

  • Advantages: Warm appearance, large variety of decors (CPL, veneer, lacquer), good repairability.
  • Application: Residential and office rooms, standard applications.
  • Please note: Sensitivity depending on the surface; check edge/moisture protection.

Steel

  • Advantages: Very robust, dimensionally stable, insensitive to impact; ideal for high frequencies.
  • Application: Utility rooms, commercial/property, technical areas.
  • Note: Cooler appearance; corrosion protection and suitable coating (powder, lacquer).

Aluminum

  • Advantages: Lightweight, low corrosion, precise profiles; modern, combines well with glass doors.
  • Use: Design interiors, upmarket residential and office applications.
  • Please note: Higher material price; careful maintenance (non-abrasive cleaners).

The right frame in 5 steps

  1. Recordwall thickness & opening dimensions exactly (incl. plaster/covering).
  2. DetermineDIN direction (hinge side: left/right).
  3. Selectframe type: Surround frame (standard), block frame (clear wall connection), renovation frame/superstructure (existing without caulking).
  4. Coordinatematerial/surface (e.g. lacquered, CPL, veneer) - to match the door leaf & handle world.
  5. Plan details: Cladding width, edge radius, sealing profile, skirting board connection.

Renovation without a building site: Superstructure, fascia boards & clean joint pattern

If the old frame is to remain, the look can often be modernized with minimal dust: With overpanel/renovation frames orcustom-made panels, you can cover the existing frame without having to chisel it out. Plan the joint pattern carefully: a narrow shadow gap between the cladding and the wall is visually calming and conceals slight reveal tolerances. Check the skirting board connection (miter, notch, end caps) so that lines run through to the wall and floor. In corridors with many doors, it looks more harmonious if the width of the cladding, edge radius and surface of all frames are coordinated - if necessary by matching the lacquer/CPL. In the case of glass doors, a cladding thickness that matches the door ensures that the fitting and frame appear close to the surface and that there are no unruly offsets.


Door frame, door handle, and fittings: It’s all about how they work together

Anyone who focuses solely on the door frame when installing a new door isn’t thinking far enough ahead. After all, a door’s appearance is always the result of how its various elements work together: the frame surface, door leaves, door handle, and fittings form a visual unity—or they don’t. A painted white door frame with a polished stainless steel door handle looks harmonious. The same frame combined with a graphite black handle creates deliberate contrasts. The key is that this choice is made deliberately and consistently.

Coordinate surface and finish: The frame sets the base color—usually white, grey, wood grain, or a painted finish. The door handle should either echo the same tone or create a deliberate material contrast. GRIFFWERK recommends: Always choose the finish of your door handle and fittings in relation to the frame color. Matte finishes (e.g., satin stainless steel or matte black) appear calmer next to structured or painted frames than high-gloss finishes—especially in modern, minimalist interiors.

Balancing trim width and hardware size: Wide door frame trims with sweeping profiles pair well with classically proportioned long backplate sets. Slim, flush-mounted frames, on the other hand—as are often installed in modern new buildings—call for equally minimalist fittings: narrow rosettes, clear lines, none of the superfluous ornamentation. GRIFFWERK offers both: from timeless classics to purist design handles, tailored to different frame profiles and door leaf thicknesses.

Tip: Plan the door frame, door leaf, handle, and Fitting together from the very beginning. What looks harmonious in the showroom or on the screen saves you from having to make corrections later—and results in a door design that truly impresses.


7 questions and answers about door frames

There are different types of Door frames, including wrap-around frames, block frames and corner frames. Surround frames are the most common and completely enclose the wall opening. Block frames sit on the wall and corner frames are installed in the corner of the wall opening.

Yes, with a little manual skill, you can install a Door frame yourself. You will need tools such as a spirit level, drill, screwdriver and assembly foam. You can usually find detailed instructions in the manufacturer's Installation instructions.

To determine the correct size, measure the Width and Height of the wall opening in which the Frame is to be installed. Make sure you also take the depth of the wall into account in order to select a suitable frame.

Minor damage such as scratches or dents can often be repaired with wood filler (for Wood) or special repair kits for Metal and plastic. For more extensive damage, it may be necessary to replace the frame.

A Door frame is the fixed frame into which a door is inserted. It includes the side posts and the upper crossbar and ensures stability and secure fastening of the door.

Door frames can be made of Wood, Metal (such as Steel or Aluminum) or Plastic. Wood is popular due to its aesthetic properties, while Metal and plastic are valued for their robustness and ease of maintenance.

Care depends on the Material. Wood frames should be wiped regularly with a damp cloth and mild detergent and repainted if necessary. Metal and plastic frames are easier to care for and can simply be cleaned with a damp cloth. Avoid aggressive cleaning agents that could damage the Material.
