Re: [EXT] Line height in resources pointed to

Also, Jeanne Spellman was the person who told me about the line-height decision, if that helps.

Sure. ri Julie Rawe 11 February 2025 at 18: 16 Hi, Ri and Jen, can I share this feedback with DJ, who is leading the WCAG 3 team that is developing guidelines for line height and other aspects of text appearance? On Tue, Feb 11, 2025 at 1: 07

Hi Ri,

I asked about this previously in AGWG and was told that the default has been to have users adjust line-height, as some other need there not to be as much spacing. Like you, I also prefer 1.5, yet there are magnifier users that prefer less. The 1.2 was a compromise between single and 1.5, I was told.

Kindly,
Jen

Subject: [EXT] Line height in resources pointed to
I followed the link to the COGA Personas document (which is good), but found it quite difficult to read because the lines were so close together.   The lines above and below tend to interfere with my reading of the current line.   Forgive me for
I followed the link to the COGA Personas document (which is good), but found it quite difficult to read because the lines were so close together.  The lines above and below tend to interfere with my reading of the current line.  Forgive me for not taking the time to look it up, but i'm trying to get some other stuff done, but felt like i ought to raise the issue.

Line height is currently set to 1.2.  Is that the recommendation?  I am able to read much more comfortably if the line height is set to 1.5 or 1.6.

By the way, line spacing requirements can be very different in non-Latin scripts.  I don't have data on specifically what the expected line heights would be for particular scripts, but i wonder whether it may be a useful exercise to see how the character heights tend to compare to Latin characters.  If you are interested, i suggest to go to https://r12a.github.io/scripts/switch.html<https://urldefense.us/v2/url?u=https-3A__r12a.github.io_scripts_switch.html&d=DwMDaQ&c=Al8V6E3U0yBSSEuVtdZbGtsvjPA49U3WmtZAsdW0D_Q&r=9YhmB_5SEixabDOvfR-id9wLtNqq8zm1GDKE6CqLIUY&m=QJLWsTXKCM_8lDwg2vAvGjAABGe9ZJMzt5tpRKVc_8_dfKTCjmN6MQMG51xYZpKU&s=m1OuG7cKgkunkLRGCsbDwYy7hYdYi6WKgcslaXy8kYM&e=> and use the pulldown to select the fragment id "Baselines, line height, etc.".  You can then select various orthographies using one of the select controls just above.  It may not, as i say, give useable data for line height preferences, but it may give you a feeling for relative glyph sizes that will help as background.

Note, also that some scripts, like Thai, generally expect additional space between lines compared to Latin text, by convention.  And other scripts such as Japanese need space for annotations to occur over/below the line without changing the height of any given line.
