Mine are all finally correct once I replaced my rear springs.

Suggestion
For those of us who are messing with suspension changes rather often, spring changes, corner balancing - it provides a known point with which to measure that removes the variability that may be seen on a given tire to assure the suspension geometry functions in a predictable way.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I don�t know if stock height is any different for wide bodies versus narrow bodies, but what exactly is stock height and how is it measured? I�m bringing my car up, and right now I�ve got 26.5 inches from the ground to the fender.

Zbomb is the source. Measuring the floor to inside includes the tire and how it's inflated. The more important measurement, to prove your springs and shocks are right is to measure from the inside of the fender, as you are doing, to the center of the center cap. Should be identical, each side.
As mentioned the correct way to measure height is to the factory points on the chassis. The fenders are convenient though.
I just measured my all stock low miles Turbo:
27" to the front fenders, 26.5" to the rear fenders.
I appriciate everyones help. I realize that there are exact methods of measuring but I'm just looking for general measurements with Stock suspension and tires. Thats good enough for me. Thanks again.
From what I am seeing from some other Posts, 26-26.5 is about average for stock. Thanks
Im 26.5 too but still the gap between tire and fender in front looks immense. People have even commented on how much higher the front sits. I recently had my suspension done, with new struts but original springs.
I just adjusted my Feal coilovers.
Mainly I wanted to get my car level.
The rear was 3/4” higher than the front.
Here’s what I think I’ve settled on:
Front
Front in metric for SoCal911t
Rear
Rear in metric for SoCal911t
It’s pretty close to stock 996 GT3 height using semi-accurate “eyeball method.”
It’s maybe 1/4” higher.
The alignment is pretty close according to my camber gauge and toe gauge.
I think I‘ll get a computerized alignment and stick with this for a while.
I hear a lot about folks chaing out their springs. Is that really necassary? In the other motosports I've been involved, it was Very rare that the springs ever sagged or needed replacing... To keep the original height that is.
People change their springs because they want to change height or change the characteristics. As you have probably seen on all the threads, there are plenty of options and configurations depending on what you want to accomplish.
My 996.2 C2 sits at 24.75 in the front and 25 at the rear with bilstein pss9s using Bridgestone RE71RS 225x40x18 front and 285x30x18 rear. Looks good, handles good, i track it and drive it around town as well. Drives like a go-cart. May or may not be your cup of tea.
What works for one owner may not work for another. Take your time and figure out what your objectives are. Suspension work is expensive, especially if you dont like the outcome and have to change it. Remember, everything you do to your 996 has trade-offs.
Yeah, I understand that. What I'm refering to is that I see A LOT of folks that purchased springs for no other reason than just refresh and replace stock with stock. In my experience that if very unnecessary but maybe OEM Porsche springs have a tendency to sag or ???
I don't know what Porsche is trying to accomplish by measuring from the ground. Tire size changes that value. Tires are different sizes even when they carry the same numbers on the sidewalls. For example in 285/30 ZR18 size the Conti Extreme Contact is 24.7" in diameter, Michelin PS 24.8" diameter, and Pirelli P Zero Rosso 25.2" diameter. That difference will throw off any measurement from the ground by up to 1/4". (That's 6.35 mm for the Euro snobs.) Then again, they have a +/-10 mm range, so it's an almost meaningless thing anyway.
Yep, alot of variables that go into it. We can spend alot of money on suspension set up including tires. Especially if we get it wrong the first time. Go too wide in the front tire versus rear and you could have nearly a 1 inch diameter differential on the rear upsetting the height, functionality and visual.
Height measurements seem to be a starting point for relative comparisons.
I think it's almost always a visual thing, and focuses on the gap between the tire and fender. Trackies will want to lower CG as much as possible while still leaving sufficient suspension travel for track work; looks are secondary. For myself it was visual, all about fixing the silly front ride height on the stock US suspension. While I was at it I wanted to improve handling too, of course.
The suspension geometry working the way Porsche intended it to is built around that measurement. If you're on a fully stock setup and can't achieve it, Porsche would say there is something wrong.
For those of us who are messing with suspension changes rather often, spring changes, corner balancing - it provides a known point with which to measure that removes the variability that may be seen on a given tire to assure the suspension geometry functions in a predictable way. In the end of the day for me, proper corner balancing takes precedence over level ride height and as a result when the suspension is setup, it is not unusual to have all 4 corners at different ride heights static. It needs to be setup to work dynamically.
I used to joke when I first got my 4S that I bought a Porsche monster truck. i look at old pics now from when i had the stock suspension and still can't believe how high it was.
I had my 1999 suspension refreshed with new shocks and some other bits. The original shocks were still on there with 100k miles. The front was so high, people on here said there must be something wrong with it. But measuring it, it is the same height as everyone else's. Even at a cars n coffee people commented on how high the front is. I wanted "stock" when I did the refresh, but I didn't anticipate what "stock" was 24 years ago!
I've noticed that the tire/fender gap looks much better (just appearance) if the wheel / tire assembly is further out (offset). the further tucked in the tires = the worse the gap looks. This is useful to me because I like the stock ride height. I don't know why but I just donot like the looks of a lowered car and I don't track. I'm just a Regular Guy.
spacers definitely help. I added them when i was still on the stock suspension (7mm front, 15mm rear), and like you said, it made the car look much better. but it still wasn't 100% to my liking, so i went with coilovers to get a minimal drop (went to 996 GT3 OEM ride height). different strokes for different folks!
I agree with you entirely that it's completely unnecessary replacing stock for stock other than having pristine powder coating on the.new items.
Porsche (as any car manufacturer, mind) uses high-quality springs that don't sag or change stiffness over time or mileage. They might settle a little at the beginning (as do their rubber sprng pads) but after that they may break due to corrosion.
Also, and I know this is going ot sound like crazy town but BLACK wheels have a tendancey to give the illusion of lowing the car. I know that sounds crazy to some but I did an experiment with my Audi TT. I went to black wheels and asked people, even performance enthusiasts, and 95% of folks guessed that the car had been lowered when I showed them the picture of the car with black wheels. Interesting to me.
Wow, I think got more than I was asking for. Thanks for the comments. I like the ride height but it makes sense and all of the other comments were well worth the read.
