"Room High" curtains / fabrics

Curtain fabrics are usually woven between 280 and 320 centimetres wide.
Width of curtain is used as the height
This equals the average height from floor to ceiling
Hence the name “Room High”

Room High curtains are often used with transparant fabrics like sheers and in-betweens.
Seams in a transparent curtain of 140 centimetres are clearly visible and this isn’t desirable.
Room High curtains are seamless. No joining seams gives it a cleaner finish.

Another advantage of Room Hight woven curtain is that you do not need to consider a pattern for the fabric.
Does this fabric have no disadvantages at all?
Yes, you can use the curtain fabric up to 10 to 20cm  from the top of the maximum height of the fabric (due to the finishing).

Room High fabrics are ideal for Roman Shades because of their unlimited width.

Room High means that you do not need to join lanes or ribs of fabric.
You can buy Room Hight fabrics depending on the width of your rail / rod times the amount a desired pleat.
After all, you already have the height from floor to ceiling.

How much fabric do you need with a room-high curtain.
Example:
Rail or row width = 300 cm.

For single pleated curtains you then need 300 cm x 2 = 600 cm of fabric.
For double or butterfly curtains you then need 300 cm x 2.5 = 750 cm of fabric.
For curtains with a triple pleat you then need 300 cm x 3 = 900 cm of fabric.

Other width ratios for your curtains are possible and can be adapted to your preferences.
The calculator next to the fabric automatically calculates the correct amount of fabric.

Calculation height: Room High curtain.
Example:

Floor to ceiling of 257 cm high.
You subtract 2 cm from the height to allow the curtain to hang freely above the floor.

For example, the height of your fabric is 280 cm.

280 cm = Height of fabric
- 18 cm. = Seam / head 8 cm for curtain tape and 10 cm for the seam.
262 cm = Maximum possible height.
255 cm = Ceiling / desired height (257 cm minus 2 cm to hang freely from the floor)
7 cm = You can cut off along these or you can add this as extra in the seam.

Does your curtain have a lead lace?
Then the calculation is as follows:

For example, the height of your fabric is 280 cm.

280 cm = Fabric height.
- 8 cm. = Head 8 cm for tape .
272 cm = Maximum possible height.
255 cm = Ceiling / desired height (257 cm minus 2 cm to hang freely from the floor)
17 cm = You can cut off along these or you can add this as extra in the seam.
