I’m fascinated by names, all sort of names, and so is my character, Thomas Radwinter in my genealogical mysteries.
In my latest novel, Thomas remarks, “What is a madcap I wonder… A fool’s cap maybe… Like a jester’s headgear the thing with bells on and is that anything to do with the old way of measuring paper, foolscap and I deviate to find other old paper sizes, octavo quarto, and would you believe it duchess, duke and Albert!”
I only had him look up a few examples of paper size, but later I went back and found out some of the sizes we used before it all became uniformly A – A1 – A5 – how dull.
I’ve missed out some, but just compare ‘A’ to:
- Emperor
- Quad demy
- Antiquarian
- Grand eagle
- Double elephant
- Atlas
- Colombier
- Double demy
- Imperial
- Double large post
- Elephant
- Princess
- Cartridge
- Royal
- Double post
- Super royal
- Broadsheet
- Demy
- Crown
- Pinched post
- Foolscap
- Brief
- Pott
If you look just on Wikipedia, not on a site which is to do with paper, there is a huge index on size:
International paper sizes
- A series
- B series
- C series
Overview: ISO paper sizes
- German extensions
- Swedish extensions
- Japanese B-series variant
North American paper sizes
- Loose sizes
- Common loose sizes
- Usage and adoption
- Variant loose sizes
- Standardized American paper sizes
- Architectural sizes
- Other sizes
- Notebook sizes
- Office sizes
- Photography sizes
- Postage sizes
- Grain
… Maybe you’re not so interested… I was… and Thomas was! Here is a link to my ebooks about Thomas, and my other books too:

It makes you wonder what size paper we think we’re looking at when we read something on a screen…

It does! When you’re writing on actual paper the size makes a big difference… I always have an A6 notebook to hand when I’m going through something I’ve written to jot things down, but never use that size at any other time!
