Flush Door Size Chart for Homes: Width, Height & Thickness Explained

Selecting the appropriate flush door is not only a matter of looks. The dimensions of the door, its width, height and thickness directly influence the fitting, ease of operation and the lifespan. Referring to the common flush door sizes at the initial stage of planning prevents problems with installation and needless changes in the future.

A clear flush door size chart makes it easier to match door dimensions with room usage, furniture flow and hardware requirements. At Greenply, we focus on offering flush doors that align with commonly used residential sizes, making it easier to select the material while maintaining consistent material performance.

What Makes Flush Doors Suitable for Homes?

Flush doors have flat panels on both sides and thus have a clean and versatile appearance. Their internal structure enables them to support laminates, veneers or paint finishes without compromising the stability.

They are usually applied to bedrooms, seating rooms, kitchens and even the main entrances in cases where heavier shutters are chosen. They are popular due to the balance they provide in terms of durability, ease of maintenance and flexibility of the design.

At Greenply, our Ecotec Flush Doors, Optima G Flush Doors, and Gold Flush Doors are some examples that provide high-performance solutions for residential doors, offering stability and long-lasting finishes.

Standard Flush Door Dimensions for Homes

Before finalising any door it is better to know the standard sizes so that the shutter is correctly fitted into the frame and operates without friction.

Width and Height Norms

Typical residential flush door sizes include:

• 750 mm width – Common for bathrooms, utility areas and compact rooms

• 800 mm width – Preferred for bedrooms and internal living spaces

• 900 mm width – Often used for main doors and wider entry points

Standard heights usually fall between:

• 2040 mm

• 2100 mm

All these dimensions are common in residential building construction, and they are compatible with standard door frames.

Thickness Options and Their Use

Door thickness determines strength, sound insulation and load-bearing capacity. Common options include:

• 25–30 mm for light internal usage

• 32–38 mm for standard room doors

• 40–45 mm for entrances and high-traffic areas

Greenply offers flush doors across these thickness ranges, allowing homeowners to choose based on usage rather than appearance alone.

E-Commerce Buying Tips for Flush Doors

Buying flush doors online or through dealers requires clarity on specifications to avoid sizing or installation issues later.

Before placing an order:

• Confirm whether the listed flush door size refers only to the shutter or includes the frame
  

• Check width, height, and thickness against the flush door size chart used by your carpenter
  

• Ensure thickness is clearly mentioned on the invoice
  

• Verify whether pricing is per square foot or per shutter
  

• Factor in flooring height and door swing direction before finalising measurements
  

Buying from authorised sellers ensures accurate specifications, proper billing, and post-purchase support.

Mistakes to Avoid When Buying Flush Doors

• Choosing door size without measuring the finished frame opening
