Serpentine Die Cut Gauging

Before, when we had lick-em and stick-em stamps, perforations were measured by digits and half-digits, such as 11X10 1/2.
Now, the self-adhesive stamps are without perforation, and the "teeth" on them are die-cut to resemble perforations. They are now measured by 1/4 digits rather than 1/2, and so, the standare perforation gauge will not measure them accurately. I've been using a " by guess and by golly" method, approximating the difference.
Is there now a standard die-cutting gauge one can get to classify the stamps more accurately ?

Yes, and it was discussed not but a week or two ago. Seems that Linn's has a peroration gauge that will measure die cuts as well. Try the Amos website,

The Linn's Multi-guage will measure to 0.1. Once you start using it you will find some of those stamps that were perf 11 really were not perf 11 but 10.9 or 11.1 depending on tool used to perforate the sheet of stamps.

Scott usually rounds to the near quarter but the actual measurement will likely be different. For example, an 11.3 will be a 11¼ in Scott and sometimes they round incorrectly.

Scott rounds perfs to the nearest half. It rounds dye cuts to the nearest quarter.

Not always. You can find an occasional 10.9, 11.1 or 11.3 in Scott. But generally, when no confusion can arise from multiple stamps with the same design, I believe your observation is accurate.

Sleepy. the die cut teeth are like the perf teeth, and the die cut valleys are like the perf holes. You can measure their gauge the same way.
