Some people hang towels vertically and some people hang towels horizontally. As to the reason it's hard to say, some people believe hanging towels in one direction or the other helps the towel dry faster.
OK. This isn't exact science, but I decided since I had two towels which were the same, to hang one vertically and one horizontally. As you can see the towels were hung on a Hills type clothes line. This was in Melbourne and the weather wasn't that great. It was a 15 degree day. There was a short shower early on but the towels wouldn't have received much rain. The following is a table of the result.
The first column is the approximate time, the second the vertical towel's weight in kg and the third is the horizontal towel's weight in kg. The weight is measured in kilograms to two decimal places giving an accuracy of +/- 10 grams.
Time, Vertical, Horizontal
10:30 am, 1.19 kg, 1.19 kg
11:30 am, 1.03 kg, 1.03 kg
12:30 pm 0.73 kg, 0.73 kg
2:30 pm, 0.67 kg, 0.67 kg
3:35 pm, 0.66 kg, 0.66 kg
I must admit I was quite surprised to see no variation in the weight between the towels being hung vertical or horizontal. I didn't expect the drying times to overly differ, but even the weight of both towels being the same at the start surprised me.
In conclusion whilst this is not exactly a scientific test, hanging towels vertically or horizontally in order to achieve a faster drying time is busted. Now if you hang them vertically to take up less space, or horizontally to keep them higher above the ground to avoid catching on something, that's a different matter.
No matter which way you hang your towels, be happy you're making the right decision.
