A few factors are involved when determining the correct shower curtain size for your installation.
Width:
1. Track Length: Measure the track length of where the shower curtain will hang. Example:1200mm + 1200mm= 2400mm (L-Shaped Track).
2. Desired Curtain Gather: Decide how much gather you would like the curtain to have; this is often a personal preference. Metlam Australia provides a standard curtain gather allowance as an example.
Once you have these measurements, you can calculate the total width of the shower curtain.
Please see the example below:
Total Width = Track Length x Curtain Gather
Example: 2400mm (track length) x 1.25 (curtain gather allowance) = 3000mm (total width of curtain required)
Length/Drop:
Drop Length of Curtain: What height is the track installed? Measure from the bottom of the shower track to the Finished Floor Level.
Please keep in mind, to allow approximately 50mm clearance from the floor to the bottom of the curtain (this ensures the curtain is not dragging on the floor creating a hazard).
Please remember to double-check your measurements and consider any variations based on the type of track or curtain you are using.
When ordering your required shower curtain, you'll need measurements of the total width and drop length of the shower curtain.
