Callipers out: what's the height of 25c vs. 28c Conti Gatorskin or Grandprix 4seasons on a narrow rim?

Could you please help me, I need to know the height in mm (measured from the top edge of the rim) of either 25-622 or 28-622 Conti Gatorskin (and/or) Grandprix 4seasons (i.e. any Conti with these dark brown crosshatch pattern sidewalls) on a narrow classic 1980s clincher rim 13mm rim like the Campagnolo Omega-V or Mavic Open4CD or the likes, measured with at least 6bars pressure?

I need to know this as I need to order tyres for my gf's bike and she wants them to be as big (comfortable) as possible but the forks allow only just above ~25mm of height.

Thanks for measuring!!!

4 seasons are almost always taller then they are wide on a 90/2000s open pro. This may be completely BS but a Highway2 (US distribution for Conti) once told me this is because Conti measures their tyres “under load” at the bottom where the tyre is touching the ground with someone on the bike.

Thanks but I need actual measurements - noone riding either of these tyres in 25c or 28c who could quickly take a measure?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
