Fullness Required

When you are choosing new curtains, one of the biggest influences on how your curtains will look is how much gather there is in your curtains.
The fullness required is the number of times you multiply the width of your window to get the gather you prefer. The fullness selections available in the calculator are to be taken as suggested fullness values only, curtain fullness is a matter of personal preference.

Please note: that whilst we recommend the following fullness, if you are having your curtains made professionally, we recommend you seek advice from your curtain maker.

Standard Heading Curtains/6" Tape

For the best results for this type of curtain aim for a fullness of 2.25. This will give a full pleat along the full width of the window. The nearer to 2.5 you can achieve, the better and fuller the curtains will look.

Eyelet Heading Curtains

For the best results with eyelet heading aim for a minimum fullness of 1.75 times the pole width, up to 2 times fullness. If you are in any doubt about the fullness with this type of heading it is best to overestimate and put more fullness in rather than less. If you are having your curtains made for you, we recommend you seek advice from your curtain maker if in doubt.

Tab Tops/Tie Tops

This style of curtain demands less fabric than normal curtains for the best look. Aiming for 1.5-1.75 times the width of your window will give the best results. When making tab top or tie top curtains you need to allow for the material for making the tabs. 0.4m of fabric per width of curtain should be sufficient for this style.

Curtains with Pelmets

If you are having curtains with a gathered valance, our experience has taught us that for the best results, you should aim for the valance to have a curtain fullness ratio of around 2.5 - 2.6. Pelmets always tend to look better with more gather.

When using a gathered pelmet you can sometimes have curtains with a lower fullness ratio of 2, but a higher ratio is recommended.

Goblet Pleat/Pinch Pleat Headings

We recommend for this style of heading a minimum fullness of 2.25 if you are using goblet or pinch pleat tape. If you are tailoring your heading using buckram as we do in our workshop, then we recommend a fullness of between 2.25 to 2.5. Again, if you are having your curtains made for you, we recommend you speak to your curtain maker as different curtain makers require different fullness when making headings of this style.
