An additional benefit of the A-Series is, that you can easily calculate the weight of a stash of paper, as A0 is exactly 1m². So if you use 100g/m² paper, one sheet of A0 weighs 100 gramms. Then you can simply divide that by 2, untill you reach the A-format you want. A1 weighs 50g, A2 weighs 25g, A3 weighs 12.5g and one sheet of A4 weighs 6.25g. So if you want to know, what a stash of 100 sheets of A4 with 100g/m² weighs, you know it will be 625g in total, without even touching a scale or a piece of paper.

Basically:
Total Weight = (Paperthickness / 2^desired A-Number) x sheets of paper.

Very useful, when you need to calculate weight for postage of paper products or how heavy a selfmade (note)book will be.

Of course the US just has to be different

The campus notebooks come in a set of five different colors so you can have one for each for your subjects

I love this. And I love that you explained the math behind it too.

[blaykebridge]

thank you so much!! in america we use letter size, but i always wanted japanese stationary but never knew what to use... i’ll probably stick to A4 or B5 thxxx

[sukmasucisafitri]

When i was a child, probably 6-7 years old there's only A5 notebooks for school. Then when i was about 9-10 there's 'adult book'. A notebook that 'can only be used' once you reach middle school. So every one who uses that kinda notebook is cool. The sizes are probably a bit smaller than B5.

And for looseleaf, when i was a child it is not used as a note, but as a collectors item. We collect and traded colorful and full of character loose leaf pages. (Aah.. the good and silly times) And the only sizes are A5. And, there's that factor where you cannot use any other note taking media besides the ol' plain notebook so loose leaf is not a popolar note taking media.

Not until i was in high school do loose leaf is becoming popular as a mean to take notes. But, not until i'm in college that the B5 sizes becoming popular and known, and being widely used besides A5 sizes, and you knoe what? I'M GRATEFUL there's B5 sizes. I LOVE IT. Now A5 sizes book/loose leaf seems to small for me :/

[CallumRickard]

My favourite size for long-form journaling is B5: the company Paperblanks make beautiful journals that are roughly this size (they call it "Ultra".) I'm thinking of starting bullet journals too, and will probably chose a B5 size over A5; for the extra little bit of space.

[perjuniper]

thank you! I've always wandered about paper size

[rykellim]

I am a frequent traveler, and I used to have different notebooks for different purposes, as suggested in the video (journal, on-the-go etc.) but eventually, I found that it is more pragmatic and time-saving to just have one-notebook-does-it-all... so now, I enter my thoughts, ideas, sketches, occasional to-do list** into an A6 notebook with a hard cover which I bring around with me nearly at all times... along with my favourite Zebra DelGuard pencil! Just sharing! **I use Google Calendar Reminders for my to-do list.

[janceerodcolegio]

my country literally has
*"short" and "long"* bond papers

a. k. a. letter and folio size

[AerisReyha]

In my place, A series is for daily use, especially A4 and A5...
B series for printing use, especially B3 or A3+, because they need margin to trim off into an A4 or A5 size book...
And F series for office and formal document, especially F4, because they need additional 2-3cm on top for office name/banner/identity...

[Tippel]

wow, I never thought anyone would need an explanation of how paper sizes work

[claudea]

perhaps you should say, that the A size is used for pages to print and the B series is used most times for envelopes. and it's really easy, for a A4 page you need a B4 envelope, for a A5 size you use a B5 envelope etc. 😊

[Kaihku]

I've made a little math and I think I've understood what's "behind" the B5 sizes.
International B5 has sqrt(2) times the area of A5.
Japanese B5 has 1.5 times the area A5.

Another kind of B5 could also be having the linear dimensions like averages of A4 and A5.
It would be a 179, 25 × 253, 5 mm and the world of paper sizes would be even more complicated =)
