If you’re installing residential, commercial or industrial doors, the term “door reveal” is one you must understand. It plays a crucial role in door fitting, frame alignment, and compliance with structural requirements. In this guide, Larnec breaks down what a door reveal is, why it matters, and how to measure it accurately — all in plain, easy to understand terms.
What Is a Door Reveal?
A door reveal is the visible section of a door frame between the wall surface and the edge of the door frame. It determines how the frame sits within the wall opening and affects door alignment, appearance, hardware placement, sealing performance, and compliance requirements.
For most Australian commercial, industrial, modular, and shed applications, reveal sizes are selected based on the total wall thickness, including framing, insulation, cladding, and internal linings. Choosing the correct reveal ensures a professional finish, smoother installation, and reduced on-site modifications.
Key Takeaways
- Door reveals affect installation accuracy and door performance.
- Reveal depth should match total wall thickness.
- Different wall systems require different reveal sizes.
- Incorrect reveals can cause alignment and compliance issues.
- Pre-hung doors simplify installation when reveals are specified correctly.
Door Reveal vs Door Jamb vs Door Frame
| Feature | Door Reveal | Door Jamb | Door Frame |
|---|---|---|---|
| Definition | Visible section between wall face and frame edge | Vertical side members that support the door | Entire structural assembly surrounding the door |
| Purpose | Provides correct wall-to-frame alignment | Supports hinges and latch hardware | Supports and secures the complete door system |
| Visible After Installation | Yes | Partially | Usually yes |
| Affects Appearance | High | Medium | High |
| Affects Door Operation | Indirectly | Directly | Directly |
| Must Match Wall Thickness | Yes | No | Sometimes |
| Important for Compliance | Yes | Yes | Yes |
Why the Door Reveal Matters
Getting the door reveal right is vital for:
– Ensuring a flush finish between the wall and the door frame
– Correct placement of hinges and latches
– Fire safety and acoustic insulation
– Aesthetic appeal and wall alignment
– Matching Australian building codes and standards
Poor reveal sizing can result in gaps, misalignments, and even failed compliance checks.
Door Reveal vs. Door Jamb: Know the Difference
– The door reveal is the space or offset between the finished wall face and the edge of the frame.
– The door jamb is the vertical part of the door frame that the door actually mounts to.
In simple terms: The jamb is the component, and the reveal is the visible space or gap around it.
Types of Door Reveals
Depending on the wall construction, door style, and use case, the reveal can vary. Common types include:
– Flush Reveal: Frame is aligned with the face of the wall.
– Setback Reveal: Frame is recessed, showing part of the wall.
– Exposed Frame Reveal: Frame is fully visible and mounted outside the wall.
Different industrial environments may require different reveal setups, especially where clean lines, fire compliance, or sealing is important.
How to Measure a Door Reveal Correctly
To accurately measure the door reveal:
1. Wait until all finishes (plasterboard, cladding) are applied.
2. Measure from the visible face of the wall to the edge of the door frame.
3. Use a level or laser for best accuracy.
4. Check multiple points — reveals can vary slightly from top to bottom.
This ensures your frames will sit flush and look professional.
Common Door Reveal Sizes (Australia)
At Larnec, door reveals are designed to suit the total wall thickness, which includes framing, linings (e.g., plasterboard or cladding), and any insulation. Common wall thicknesses — and therefore common reveal sizes — include:
-90mm wall thickness – Typical for steel frames and lightweight construction (e.g., internal walls or sheds)
-100mm–120mm wall thickness – Common in modular buildings and insulated panel systems
-150mm+ wall thickness – Used in heavy-duty, double-skin, or acoustic/fire-rated wall constructions
Always check wall build-ups, insulation type, and whether architraves are used.
Reveal Sizes and Door Types
Reveal (wall thickness) requirements vary depending on the door type and installation environment:
– Personal Access Doors: Typically suit 90–120mm wall thicknesses
– Fire Rated Doors: Often require deeper reveals to accommodate fire seals and compliance features
– Industrial Steel Doors: May need setback reveals for external or exposed-frame mounting
– Modular Buildings: Often need custom reveal depths for panel systems
Installation Tips from Larnec
– Always allow for the total wall thickness, not just the structural framing.
– Choose a reveal size that minimises trimming and fitting on site.
– Order pre-hung door systems with correct reveals to save time.
– Talk to your door supplier early if wall specs are still being finalised.
Typical Door Reveal Requirements by Building Type
| Building Type | Typical Reveal Consideration |
|---|---|
| Residential Homes | Match plasterboard and timber frame wall thickness |
| Commercial Buildings | Accommodate steel framing and wall linings |
| Industrial Facilities | Consider insulation, cladding, and durability requirements |
| Modular Buildings | Often require customised reveal depths |
| Shipping Container Conversions | Custom reveals frequently required |
| Fire-Rated Installations | Additional depth may be required for seals and compliance |
Don’t Overlook the Door Reveal
The door reveal might seem like a minor detail, but it can make or break the success of an installation. By measuring accurately, understanding your frame and wall setup, and choosing the right reveal type, you’ll ensure a compliant, clean, and professional finish. At Larnec, we’re happy to advise on reveal sizing, pre-hung solutions, and custom framing systems for your project. Need help choosing the right reveal size? Contact us for expert advice!
Frequently asked questions
A door reveal is the visible portion of the door frame between the wall face and the frame edge. It helps ensure proper door positioning, alignment, and finishing during installation.
The correct reveal helps maintain alignment, improves appearance, supports hardware installation, and reduces the risk of gaps, binding, or compliance issues.
Measure from the finished wall surface to the edge of the installed door frame. Measurements should be taken after cladding, plasterboard, or wall linings have been installed.
Most lightweight steel-framed walls and shed applications use reveal sizes designed around a total wall thickness of approximately 90mm, although exact requirements depend on the wall build-up.
A reveal that is too small may result in installation difficulties, poor alignment, visible gaps, hardware interference, or additional site modifications.
A reveal that is too large can create finishing issues, affect aesthetics, and require additional trims or architraves to achieve a professional appearance.
Yes. Fire-rated doors often require specific frame configurations, clearances, and reveal dimensions to accommodate seals and compliance requirements.
Industrial doors may require larger or customised reveals depending on wall construction, insulation requirements, external cladding systems, and structural conditions.
Yes. Many pre-hung door systems can be manufactured with custom reveal depths to suit modular buildings, insulated panels, tilt-panel structures, shipping containers, and specialised industrial applications.
Yes. Specifying the correct reveal during manufacturing reduces installation time, minimises site adjustments, and helps achieve a cleaner finished result.
