A lot of sellers and manufacturers suggest 10 metres but we think that the figure they provide is too restricting for real-world use, there is simply not enough room to grow. To give you an example, if you have a family of four an airer with 45 to 50 metres of drying line space should be more than adequate.
As we have mentioned earlier, you will be drying your clothes indoors so you will be relying heavily on air movement or dehumidification courtesy of your home’s air conditioner, do not expect drying times to be as fast as it is outdoors.
Opt for a model that has four or five lines but with a cabinet width of 800mm and above, most models that fit this criteria have adequate amount of space between each drying line and trust us, you will want to stick with this formula.
Adequate amount of space between drying lines is crucial. For outdoor units we typically recommend around 130 millimetres or so which is quite dense but you can go less than that it is completely fine because outdoor drying lines can take advantage of the constant airflow, stable humidity levels, and intense heat from the sun.
Indoor retractable washing lines do on the other hand should not have less 140 millimetres of gap between each line if at all possible, this will inhibit the drying performance of your clothesline and you do not want that to happen.
When drying indoors, our clothes are not exposed to sunlight for sterilization and the humidity can be quite hard to control, this is a perfect recipe for odour causing bacteria or moulds to grow and nobody wants that to happen.
If you have no choice but to go with something less than 140 millimetres, you will have to rely on a fan, dehumidifier or strategically place your indoor retractable clothes line near an air conditioner’s intake/outlet vent or window.
