What is Curtain Fullness & What Fullness will my Curtains be?

What does curtain fullness mean and how much do I need? Curtain fullness refers to how much fabric is used compared to the width of your curtain track or pole. More fullness creates deeper pleats and a more luxurious finish when the curtains are closed. At Direct Fabrics we manufacture most made to measure curtains as standard using 2x the track width , also known as double fullness . This is the industry standard for pencil pleat and eyelet curtains, and means you do not need to calculate or choose fullness unless you want something different. We automatically allow for the correct amount of fabric and round up widths where needed to ensure the best finish. Certain heading styles, such as pinch pleat or wave, require more fabric due to how the pleats are formed, and are handled automatically based on the heading you select. For a visual explanation, examples and guidance on how fullness affects the appearance of your curtains, see our full guide on Understanding Curtain Fullness .

How do I calculate how much curtain fabric I need?

Expectation setting: This is a dimout wool serge supplied as fabric (unlined). It provides strong masking and light reduction, but it is not a guaranteed total blackout solution. For complete blackout, specify an appropriate blackout lining (see spec tab for supporting documents and certificates).

Why specify Kilo Black Wool Serge (840gsm)

Kilo Black Wool Serge is a heavyweight, high-density woven wool serge used as an industry-standard black masking fabric for events and stage environments. The 840gsm weight is selected where a more substantial drape and hard-wearing performance are required.

It is specified for applications where sound control is helpful: the product listing notes it is designed for acoustic performance and can help reduce echo and reverberation within a room. The product page lists an Acoustic Absorption Rating: B Rating.

Flame retardancy is stated as inherently flame retardant and certified to BS5867: Part 2:2008 Types A, B & C and EN13773 Class 3. Certificates and supporting documents are available in the spec tab for tender packs and compliance files.

Where this fits in our range

Choose Kilo (840gsm) when you need a heavier black wool serge for stage masking, durability and dimout privacy, with the acoustic benefit noted on the product listing. If your priority is a lighter-weight wool serge for easier handling or different budget points, select an alternative wool serge option in our range.

Best suited for

Stage masking and black drapes where a heavier cloth is required
Events and production environments needing robust dimout fabric
Spaces where echo control is desirable (refer to the listed B rating in specs)

For specification-critical projects, confirm certificates, care guidance and any site-specific compliance requirements in the spec tab.

Who uses Kilo flame retardant black wool serge

Commonly specified across events, theatre/stage and production environments where black masking is required, with additional benefit for spaces aiming to reduce echo and reverberation.

Also used in commercial and public interiors where a dimout fabric is needed for privacy and light reduction, and where documented flame retardancy to British and European standards is required.

Dimout vs blackout clarification

This fabric is listed as dimout (unlined). If your brief requires maximum light exclusion, specify a blackout lining solution to suit the end-use and cleaning regime. Our team can advise on lining options; supporting documents can be referenced from the spec tab.
