You could make some legal 2" numbers, with these being additional "artwork". But I personally believe that doing it once, per regs, is the right answer.

In a lot of different font styles (maybe all), it is very common for the letters of the alphabet to not all be the same hight.
Adjustments are made to some of the letters so that to our eye they all look the same size. Apparently, the large variation in shapes will trick out eye to thinking they are not the same hight, when they really are. This needs to be considered when ordering lettering.

Exactly, which is why you need a geometric font and not one that is visually corrected...

I challenge anyone to find another standard font that meets (exactly) the FAA letter width and stroke width requirements as the correct fraction of letter height.

This was ACS' N-number strip - not individually ordered characters.
But your point is well taken. Even ordering N-number decals from a well known supplier isn't a guarantee of accuracy.

I am not aware of any legal 2" numbers. They need to be at least 3".

Question about ?NX? on N Number.
I am building an RV-4 and have been thinking about using the ?NX? on my N number to specify experimental. My question is this
When I use the N number during radio calls, do I say
November-one-two-three-alpha-bravo
Or
November-Xray-one-two-three-alpha-bravo
Or
Experimental November-one-two-three-alpha-bravo
Thanks for any help.

2" numbers may be used on the RV-3 and -4 per 45.22(b), but not the RV-10, as in this case.

When using the "NX" number on the aircraft, the "X" only replaces the 2" "experimental" placard.
The "X" does not show up in ANY paperwork, or within ANY radio communications.
