View Full Version : Watercolor/Drawing - Paper Sizes

11-25-2004, 07:45 AM
"The only dumb question is the one you didn't ask." ... Heard all my life.... SO

I remain totally confused by the different US, Brit and Euro paper sizes mentioned in nearly all threads...

I know 5"x7", 8'x10", 12"x 14"/12"x17", 16"x20" and up.
I have no idea what A2,A3,A4 sizes are...
I have no idea what quarter sheet, half sheet, full sheet sizes are...

Can someone please relieve my ignorance/lack of knowledge on this? A PM would be sufficient, no need to post (unless there are others who also may not know this?}

Hi Jo ... Happy Thanksgiving!!

I'm not sure myself what A3, A4, ... are :confused:

But the quarter, half and full sheet refer to a full sheet of watercolor paper that is 22" x 30" (558mm x 762mm) and is used either 'full' (the whole sheet) or 'half' (cut in half which I've always assumed is 22 x 15 but I suppose might also be 11 x 30.) or quarter (cut into 4 pieces, each one 11 x 15).

Hmmmm, I'm sure of the 'full' sheet, that's an easy one. :p I'm sure about the 'quarter' sheet. But now I've confused myself about what, exactly, is meant be a 'half sheet'! :eek: :confused:

Jiminy Cricket, I should have waited for someone who actually knows what they're talking about to answer this question ... :D

The sizes are converted here (http://www.syscontech.com/supply/papersize.htm) on this table.

Hope it helps. The A series is at the end.

Henry's below is clearer for the metric to inches conversion.

Hello Jo

A0, A2, A3 etc are Metric paper sizes, the link below explains all


Quarter/Half sheets etc refer to sizes of a standard Imperial paper 30x22 inches, so obviously a half sheet is 15x11 inches

I thought 15x11 was a quarter sheet 'cause you cut the full sheet in half and then cut each half in half again?...

Thanks for the explanations. After reading this thread I made a scheme showing how the paper sizes compare. I post it here because I think it can be useful for other people too.

P.S. Sorry that the picture is rotated, it's 522x374 but the limits here are 500x600...

Veronika, Thanks!! I am copying and saving your example... Isn't WETCANVAS just the greatest, whether your question/need is
big or small? I love it! :clap: :clap: :clap:

Glad you asked Jo :)

Great scheme Veronika - I have printed it out and taped it up on the wall in my temenos.

Another configuration for a half sheet is to tear it 30x11 instead of 22x15. Makes a nice long piece for a panoramic scene (or a long, uncoiled snake :D ).

Jo and Norah, I am glad that you find the scheme useful. At least someone has my work on their wall. ;)

A1 is 23" x 33"
Imperial is 22" x 30"

So they are very similar in size.

A1 cut in half = two sheets of A2
A2 = two of A3
A3 = two of A4
A4 = two of A5

A2 23" x 16" Half Imperial 22" x 15"
A3 16" x 11.5" Quarter Imperial 15" x 11.5"
A4 11.5" x 8" Eighth Imperial 11.5 x 7.5"
A5 8" x 5.5" 1/16th 7.5" x 5.75"

The whole system breaks down when European manufactures sells paper at 50 cm x 70 cm (19"x29")!!!!!!!!!!!
This is not the A-x metric paper system
