Miles doesn't go very deep into the idea of how big a note ought to be, only that the system "encourage[s] a business-like brevity."

Miles goes against the grain of using "cards of equal size", but does so to emphasize the affordance of using them for "Arrangement and Clearness".

Here Kaiser touches on the broader themes inherent in the concepts of atomic notes, which might be used to build up new and interesting structures. He doesn't specify the "size of a note" nor does he say that one will "know it when they see it", but he's suggesting something very close to it.

Rather than define the appropriate size, a feat which is difficult to do at best, he's providing a very narrow set of benefits for encouraging one to cut things down to size as they index them: small pieces are easier to use to build new things.

• many different definitions of notes (types...)
• Damien Newman scribble drawing as a representation or diagram of the design process (22:42)
• 2x2 grid matrix of evergreen versus transient and mnemonic versus generative.(27:00)

• contacts, recipes, book highlights and marginalia in the mnemonic/evergreen quadrant; to do lists, grocery list, appointments in the mnemonic/transient quadrant; sticky notes, mind maps, project plans, tinderbox in the generative/transient quadrant; knowledge gardens, zettelkasten, pkm systems in the generative/evergreen;

• What does the structure of containers in each of these spaces look like? How simple or complex are they?

• There can be growth from one space into others, (especially from the mnemonic into generative).

• Chuck Wade mentions that email fits into all four of the quadrants.

• Cathy Marshall used "information gardening" in Xerox Park setting... (source?) It may have been mentioned in Arango's interview of Mark Bernstein on The Informed Life.

Arango came to knowledge gardening via Brian Eno essay on architecture and gardening metaphor.

Three Rules of Knowledge Gardening

1. Make short notes; create enough context to help out your future self
2. Connect your notes
3. Nurture your notes; revisit, build, feedback

suggestion of recombination of individual notes using cards to create something new

(have I remarked on this in krajewski?) ᔥ Johann Jacob Moser commented on the ability to breakdown bodies of information into smaller pieces that might be reshuffled into new configurations as one might in a 'game of cards'.

Gotthard Deutsch didn't adhere to any particular theory of information when it came to the size of his notes. Instead Jason Lustig indicates that his perspective was influenced by his personal motto 'de minimis curat historicus' (history's minutiae matter), and as a result, he was interested in the smallest of distinctions of fact and evidence. ᔥ

Here the writer, who doesn't lay out any of the general principles of a zettelkasten practice, automatically presumes one idea per card (presumes it from where? zeitgeist) and then jumps into the question of note size and other semantics.

reply to u/ManuelRodriguez331 at https://www.reddit.com/r/Zettelkasten/comments/15ehcy5/why_is_the_index_card_half_full/

There has been debate about the length of notes on slips since the invention of slips and it shows no signs of coming to broad consensus other than everyone will have their personal opinion.

If you feel that A6 is is too big then go down a step in size to A7. One of the benefits of the DIN A standard is that you can take the next larger card size and fold it exactly in half to have the next size smaller. This makes it easier to scale up the size of your cards if you prefer most of them to be smaller to save space, just take care not to allow larger folded cards to "taco" smaller cards in a way they're likely to get lost. If you really needed more space, you could easily use an A1 or A2 and fold it down to fit inside of your collection! (Sadly 4x6 and 3x5 cards don't have this affordance.)

Fortunately there are a variety of available sizes, so you can choose what works best for yourself. Historically some chose large 5x8", 6x9", or even larger "slips". Some have also used different sizes for different functions. For example some use 3x5 for bibliographic cards and 4x6 for day-to-day ideas. I've seen stacked wooden card catalog furniture that had space for 3x5, 4x6, and 8.5x11 in separate drawers within the same cabinet. Some manufacturers even made their furniture modular to make this sort of mixed use even easier.

One of the broadly used pieces of advice that does go back centuries is to use "cards of the same size" (within a particular use case). This consensus is arrived at to help users from losing smaller cards between larger/taller cards. Cards of varying sizes, even small ones, are also much more difficult to sort through. Slight of hand magicians will be aware of the fact that shaving small fractions of length off of playing cards is an easy way of not only marking them, but of executing a variety of clever shuffling illusions as well as finding some of them very quickly by feel behind the back. Analog zettelkasten users will only discover that smaller, shorter cards are nearly guaranteed to become lost among the taller cards. It's for this reason that I would never recommend one to mix 4x6, A6, or even the very closely cut Exacompta Bristol cards, which are neither 4x6 nor A6!

I once took digital notes and printed them on paper and then cut them up to fit the size of the individual notes to save on space and paper. I can report that doing this was a painfully miserable experience and positively would NOT recommend doing this for smaller projects much less lifelong ones. Perhaps this could be the sort of chaos someone out there might actually manage to thrive within, but I suspect it would be a very rare individual.

As for digital spacing, you may win out a bit here for "saving" paper space, but you're also still spending on storage costs in electronic formatting which historically doesn't have the longevity of physical formats. Digital also doesn't offer the ease of use of laying cards out on a desktop and very quickly reordering them for subsequent uses.

There are always tradeoffs, one just need be aware of them to guide choices for either how they want to work or how they might work best.

Personally, I use 4x6" cards because I often write longer paragraphs on them. Through experimentation I found that I would end up using two or more 3x5 cards more often than I would have had mostly blank 4x6 cards and used that to help drive my choice. I also find myself revisiting old cards and adding to them (short follow ups, links to other cards, or other metadata) and 3x5 wouldn't allow that as easily.

As ever, YMMV...

Early library card catalogs used cards that were 2 x 5" cards, the Harvard College size, before the standardization of 3 x 5" index cards.

questions:

• What were the exact sizes of the slips? Had they been standardized at the time?

Q: Can I use a card index for note taking?

ChatGPT does a reasonable bit of advice on how one would use a card index for note taking.

Relying on cut up slips of paper rather than the standard cards of equal size, Keith Thomas has relayed that his slips often "get loose and blow around the house, turning up months later under a carpet or cushion."

He also suspects that some of his notes have accidentally been thrown away by falling off his desk and into the nearby waste basket which camouflages his notes amongst similar looking trash.

While he previously recommended using note cards of the same size, the examples in Goutor (1980) have 3x5" cards for bibliographic notes and 5x7" or larger cards for content notes. (p19, 21)

Is there a reason stated anywhere here for this discrepancy or change? One would ostensibly keep them in different places/sections of one's card index, but does the size difference help to differentiate the two to aid in sorting? Is the larger card intended to hold more long form writing?

Goutor is in Canada, so were 5x7" cards more common or standardized there in the late 1970s and early 80s?

A5 measures 148 × 210 millimeters or 5.83 × 8.27 inches, so is a bit larger than 5x7".

5x7" is a more standard photo size, so was this chosen as the result of storage options from the photography space?

5x7" is scantly available in America in 2022, but only from Hamilco. A few others make cardstock in that size but not specifically as index cards.

Goutor comments, like many before him, that it is common to take notes on notebook paper in longer form, but that this is inadvisable as it is much harder to impose a useful order or classification on such work. He does mention scissors as a means of cutting up such notes, but comments that "a mass of slips of paper of varying sizes [can be] difficult to arrange and potentially useless unless care has been taken to note the source of each separate entry."

He also repeats the frequent admonitions that one should take notes only on one side and to use cards of a uniform size.
