I would say roughly, erring on the side of caution and not wanting to be too specific or scientific but at the same time realistic, and obviously on a wholly personal front and in my own honest and firmly held belief around 1mm.

Yes this has happened to me all be it a long time ago when all tents were canvas. We were on a canoe camp with about 20 tents in a field next to the river, it didn’t stop raining the whole time we were there. All the others were sleeping on the floor or on camp beds and when the river burst it’s banks they soon found out & evacuated the field, I was sleeping blissfully on my airbed which started to float within the tent. I awoke in the morning & could still hear the rain on the outside of the tent but wasn’t bothered because I was still dry & snug in my bed. That was until I went to get out, yes the water was knee deep & my tent was the only one left in the field & as I looked out there was everyone else standing on high ground laughing at me but at least I had a good nights sleep so I had the last laugh.

I’m not a complete idiot, some parts are missing!
It's a fact...you can have a flysheet made of top quality 5000HH material but as soon as you put a seam in it, you're punching it full of holes. It's very rare for a tent to leak directly though the canvas and very common for it to leak through seams and zips. Thing is you can tape and seam seal the seams six ways till Christmas but pitching a tent can and does stress the seams and sometimes a couple of stitching holes open again, even in the best tents. And the more seams you put in a tent the more chance there is of this happening. I've seen tents with window panel + mesh panel + zip down outside panel + inside curtain panels...ie four sets of seams round the same area, and half odf them with zips too. No wonder the bloomin' thing will leak...that's not a flysheet, that's lacework!
My advice? If your leaks are definately not caused by condensation, they're only miniscule ie a couple of drops, you can see daylight at a couple of stitch holes and you're otherwise pleased with a tent...seam seal it and get on with camping.

Yup thats happened to me too!!! was fun..... air beds float.........
when is too much though..... well TBH as long as the tent stays dry id say it doesnt matter really... last summer it was sunny for 2 days out of 2 weeks and it didnt bother us too much...
I have just returned an Outwell Nebraska XXL from 2007 as it leaked. I got store credit as it was more than a year old but will now have a dry tent.
We tried sealing the seams and fabsil but I am sure you know due to the size of the tent this is difficult. Nothing worked. The entire grey fabric leaked.
I'd not be happy with any tent leaking. However, I can see how it would come about - the tent I've just bought cost me £100 from Decathlon. The last tent my mum bought was less complicated (no window hatches etc) but was getting on for £200 something like 18 years ago. When £200 really was a fair whack of cash. And that was a cheap tent. And no, it never leaked.
IMO something has to give somewhere as prices come down, just like it has done with clothing. My Aunt used to work at Courtaulds back in the day, and stuff was required to have 16 stiches per inch. The stuff you see in the shops now is more like 6...
this is why i only use cabanon and the good news is they have been saved see in latest camping magazine!The laguna i have at the moment is polycotton not as good as my etna for breathing but stood up to heavy rain on my honymoon i would not think of anything else!
