I am always forgetting the sizes for A paper, this is so annoying that I keep a small chart on the print cutting table so when I am ordering frames for an exhibition or display items for conferences or retail display etc. Nothing special, i can often remember them all, but it saves time and doubt if i can have these all important measurements close at hand, but today my trusty laminated chart has disappeared AGAIN!! I blame shooter 4 who is always leaving things on location that have no right to be there in the first place, so my chart is probably in Morocco right now, along with a 90mm pentax 67 lens that was left there too… ahhhh

So that I will never loose it again, I am putting one here online in our diary section for myself to have access to 24/7 and all of you too… Enjoy

The interesting thing about the A ratios are that they are not made in the so called Golden ratio 1.61803399  (sexy no?) This ratio is the one that looks the most pleasing to the eye, according to countless generations of artists and mathematicians, personally i am not convinced, but maybe we have just been over exposed, I so far have never found a ratio that i can say I like a lot more than this though… A paper is made in the ratio of 1.4142 or the square route of 2 not quite so sexy but very interesting never the less.

the other point to note is that each size is exactly twice the area of the preceding one, and as the ratio is preserved you can make the previous one by folding in half in the middle. This chart should show the whole thing as well as “legal” or foolscap (what ever that was)…

    Hi, really like the appearance of the image of the girl, can I ask what you guys would charge for something similar? I have a total budget of $6000 inc my flights to London, will that be enough?

    You guys are obviously slightly mad, but equally obviously genius Photographers. I found this post to be handy as I always forget these ratios and in a surreal way it is insightful too. Now I know where to come for the A4 sizes next time i forget and some photography for our agency 😉 I absolutely adore your blog!

    I’ve been surfing online and In my opinion, if all website owners and bloggers made good content as you did, the web will be much more useful!
