Next to an 11 inch paper towel roll. With a lot of coaxing, it barely made it to the end of the roll.
Point 1 :
Household or kitchen towel rolls of A-brands are just over 9".
Point 2 :
They have the same tube diameter as toilet paper tubes for all A-brands. (girth of 143mm = +/- 5.25")
Of course there are exceptions even in the same brand between Europe and the US. But most paper compagnies like ( KC, Scott, Page, Servus, ... ) follow those standards. [ following the dimensions of the holders of those items ]
PS :
- In your pic the dimensions can be seen by comparison. ( finger length / towel length )
- The print shows a KC or Scott ( = KC ) towel.
