Data for

• % of sessions which do not use the default width option (and view the site at full width) Vector22 [INTERIM REPORTING NEEDED for sessions where viewport => 1200px]
• % of sessions using a non-standard font size (on Minerva) [INTERIM REPORTING NEEDED]

...can be found in this sheets file.

Update: T349862 is impacting data reporting.
From @KSarabia-WMF: The discrepancy noting that the majority of logged-out users are using the small font size is due to a mismatch in the HTML form where the small value is labeled as "Standard" in Minerva.
In Desktop, the default and "Standard" is "1".

Hi @KSarabia-WMF, can you clarify the font values captured in event.MobileWebUIActionsTracking schema for each font option below? What's the default value? Are these values consistent across logged-in and logged-out users? The info will help me understand whether we can adjust the results using the current data.

Font Options and Their Captured Values (UPDATED)

1. Minerva (Mobile):
   • Standard (Default): small
   • Medium: regular
   • Large: large

2. Vector (Desktop):
   • Small: 0
   • Standard (Default): 1
   • Large: 2

Default Value

• Minerva (Mobile):
  • The default font size for logged-out users is small (Users see this as "Standard").

• Vector (Desktop):
  • The default font size for both logged-in and logged-out users is 1 (Users see this as "Standard").

Consistency Across Logged-In and Logged-Out Users

• Logged-In Users:
  • Font values are correctly captured based on user selection.

• Logged-Out Users:
  • In Minerva (Mobile), the default value is small (Users see this as "Standard").
  • In Vector (Desktop), the default value is 1 (Users see this as "Standard").

Summary of Findings

1. Font Values Captured:
   • Minerva (Mobile):
     • Standard (Default): small
     • Medium: regular
     • Large: large
   • Vector (Desktop):
     • Small: 0
     • Standard (Default): 1
     • Large: 2

2. Default Value:
   • Minerva (Mobile): Default for logged-out users is small (Users see this as "Standard").
   • Vector (Desktop): Default for both logged-in and logged-out users is 1 (Users see this as "Standard").

3. Consistency:
   • The captured values are consistent across both logged-in and logged-out users are currently inconsistent. A ticket is in the works to fix this.
4. Context:
   • The issue is that we kept the legacy 14px value in vector as a small. So the "Standard" was the second biggest size. In Minerva, it was already 16px, which we wanted as the new default and didn't want anything smaller.

@jwang See the write-up above

@KSarabia-WMF , thanks for taking a look. I am confused. I did not see some of the values you listed for Minerva (Mobile) on interface and schema. Can you double check?

What I observed for Minerva (Mobile):
On interface: standard, medium, large
Values in schema: regular, large, small, 0

@ovasileva, @KSarabia-WMF
Can you provide the timeline of the deployments? Any other changes to existing features?

I've noticed a significant change in the font feature trend on desktop: the numbers of small font (0) and standard font (1) altered dramatically around June 12. It appears that the default value may have been changed around that date. If this is the case, we may need to adjust our analysis window due to caching issues.

@jwang Sorry, you're right. I am confusing myself. standard, medium, large is what is on the interface.
For the following

Values in schema: regular, large, small, 0

where are you seeing that/what are you referencing?

where are you seeing that/what are you referencing?

The value captured in schema event.MobileWebUIActionsTracking

The query I used:

> SELECT distinct  event.font
> FROM event.MobileWebUIActionsTracking
> WHERE year=2024 and month=6 
> AND event.action='init'

@jwang I've updated the comment above with the correct values. Again, sorry for the confusion. The results of that query looks as expected.

Vector (Desktop):
The default font size for both logged-in and logged-out users is 1 (Users see this as "Standard").

@KSarabia-WMF, Can you double check the default font value of logged-in on desktop? The below graph shows more sessions with font of 0 than 1. It seems the default value is different for logged-in and logged-out.

@KSarabia-WMF, Can you confirm whether the below instrumentation mapping table is correct for mobile Minerva users?

Is the default same for desktop users?

Here is the analysis summary of font menu. CC @ovasileva

Methodology

The non-default font rate was defined as the ratio of unique sessions with a non-default font size to the total number of unique initialized sessions per day. We analyzed the daily average over a specified timeframe.

Mobile web (Minerva skin)

Analysis request: % of sessions using a non-standard font size (on Minerva)
Summary:

• For logged-in users on mobile, the non-default font rate is 2.052%
• For anonymous users on mobile, the non-default font rate is 0.015%

Compared with baseline

Note:
The default value changed since our baseline analysis. In baseline analysis (T346979) , the default font is Medium ( schema value: regular). In the year-end analysis, the default font is Standard (schema value: small).

Desktop (Vector2022 skin)

Analysis request: % of sessions which have set a non-default font size (Vector22)
Deployment note: deployed by tiers. It has been fully deployed on all wikis by Jun 11 (T362148#9879986)
Summary:

• For logged-in users on desktop, the non-default font rate is 13.29%
• For anonymous users on desktop, the non-default font rate is 8.00%

Compared with baseline

Here is the analysis result of color-theme (dark mode) and overall on Mobile web (Minerva skin). cc @ovasileva

Methodology

The non-default color-theme rate was defined as the ratio of unique sessions with a non-default color-theme setting to the total number of unique initialized sessions per day. The non-default settings include: Dark and Automatic.
The over-all non-default rate on mobile was defined as the ratio of unique sessions with a non-default setting of font size OR color theme to the total number of unique initialized sessions per day.
We analyzed the daily average over a specified timeframe.

Results

Analysis request: % of sessions using non-default color mode (on Minerva)
Summary:

• For logged-in users on mobile, the non-default color-theme rate is 2.83%.
• For anonymous users on mobile, the non-default color-theme rate is 0.18%.

Analysis request: Overall % of sessions with adapter non-default experience on Minerva skin
Summary:

• For logged-in users on mobile, the overall non-default rate is 4.63%.
• For anonymous users on mobile, the overall non-default rate is: 0.20%.

Here is the analysis result of color-theme (dark mode) and overall on desktop. cc @ovasileva

Results

Summary:

• For logged-in users, the non-default color theme rate is 7.04%
