Quick Answer
Personal access door sizing affects more than opening width. Correct specification needs to consider wall depth, clearance requirements, pedestrian flow, frame integration, hardware compatibility, and how the opening will function in day-to-day operation. Larnec manufactures pre-hung personal access doors in standard and custom dimensions to suit practical site requirements across a wide range of industries.
Standard Sizes That Simplify Specification
For many projects, standardised sizing keeps procurement straightforward and installation predictable.
Larnec’s common personal access door formats include:
- 2040mm height
- 820mm widt
- 920mm width
- 1100mm width
These widely specified dimensions suit many commercial and industrial openings, allowing builders and project managers to align framing, hardware, and access planning earlier in the build cycle.
For repeat-build programmes, standard sizing can also reduce specification friction across multiple sites.

Size Selection Should Match Operational Use
Door width is often selected by habit rather than by function.
The better approach is specification by use case:
- 820mm – practical everyday personnel access
- 920mm – improved accessibility and easier movement
- 1100mm – wider clearance for equipment, PPE movement, or higher foot traffic
- Custom widths – specialist access requirements, oversized openings, or operational design needs
Choosing size based on operational movement improves workflow, usability, and long-term practicality.
Opening Depth and Wall Construction Matter
Correct door sizing is not only about width and height—it must also suit wall build-up.
Specification should account for:
- Stud wall construction
- Steel framing systems
- Tilt panel openings
- Modular wall assemblies
- Cladding thickness
- Internal lining build-up
- Frame fixing method
Matching the jamb and frame configuration to the wall system helps avoid on-site modification, reduces install complexity, and improves finish quality.
This is particularly important on commercial projects where consistency across multiple openings matters.
Custom Dimensions for Non-Standard Openings
Not every project fits a standard opening schedule.
Larnec can manufacture personal access doors to suit:
- Narrow access openings
- Oversized pedestrian openings
- Increased door heights
- Wide access points
- Double door arrangements
- Retrofit replacement openings
- Specialist modular dimensions
For architects and specifiers, this flexibility allows the door system to suit the project—not the other way around.
Door Size Influences Hardware Performance
Larger openings place different demands on hinges, closers, locksets, and overall door operation.
As dimensions increase, specification may require consideration of:
- Hinge loading
- Door weight distribution
- Closing force requirements
- Lock alignment performance
- Opening clearance radius
- Seal compression consistency
Proper sizing supports better operational performance over the life of the opening, particularly in high-use commercial and industrial settings.
