There's no official measurement which mugs have to adhere to. The original 10oz Tams Durham mugs which here manufactured in the UK were small looking compared to today's 10oz mugs. Listawood's original 10oz mugs were identical, but even those have increased in size in recent years. These would be the Thai made Xpres style mugs. If you measure the capacity, I think they are about 10-11oz...it was years ago when I actually done this, so if somebody has nothing to do, you can confirm this! A 10oz Xpres mug weighs 11.2 oz just to confuse you.webtrekker;141033 wrote:I can't understand why they call these 9oz mugs then. That's the standard size of most 11oz mugs. I always believed the 'oz' stood for fluid ounces, ie. the capacity of the mug.
The original smaller 10oz mugs were squeezed out of the market by bigger and uglier 11oz Chinese builder's mugs. The Xpres/ Listawood 10oz mugs are somewhere in-between with small handles. These 10oz mugs are for the European market usually. I'm rambling on now.
