Teiler calculator: convert Teiler to tenths and rings

September 18, 2026 · 4 min read

How the calculator works

First you pick the face: air rifle 10 m, air pistol 10 m, smallbore 50 m or Scheibe 4 for 100 m rifle and 25 m precision pistol. The projectile diameter is prefilled per face, 4.5 mm for air rifle and air pistol, 5.6 mm for the .22. You can change it, say for a 7.8 mm centerfire standard rifle on Scheibe 4.

Then you enter your Teiler. The calculator shows the decimal score and the full ring, plus whether the shot counts as an inner ten. In the other direction you enter a score like 10.4 and get the Teiler range it sits in. For a club match with a Teiler factor there is a separate field, divide or multiply, and the converted Teiler appears next to it. The inputs are part of the page address, so you can pass a result on as a link.

Three examples

The table works through three values as they appear on printouts and displays. In brackets is the inner-ten limit of that face.

If you set the Teiler factor for the air pistol to divide by 3, a converted value of 100 T appears next to the 300 T. On the rifle face, 100 T would also be a 10.6. Purely by geometry the factor would be 3.2, because a tenth measures 80 Teiler on the pistol face and 25 on the rifle face. Clubs work with values between 2.6 and 3.0.

The math behind it

A shot scores a ring as soon as the edge of the shot hole touches the ring line. On the air rifle face the ten therefore reaches to 250 Teiler, 25 Teiler of ten-dot radius plus 225 Teiler of pellet radius. Every ring is split into ten zones of equal width, 25 Teiler on the air rifle face and 80 Teiler on air pistol and 50 m smallbore, and the upper limit still belongs to the better score: a 25.0 Teiler is a 10.9, a 25.1 a 10.8. The result is truncated after the first decimal place, so 10.452 becomes a 10.4. On Scheibe 4 the ten is a circle of 50 mm, as wide as the distance from ring to ring. Its zone runs from the center to the touching limit, 25 mm plus the 2.8 mm bullet radius, which is why a tenth there measures 278 Teiler and 250 from the nine outward.

Tables to look things up

If you would rather look things up, every zone is in the air rifle Teiler table. For the pistol there is the air pistol Teiler table with 80 Teiler per tenth, and the smallbore Teiler table covers 50 m smallbore and Scheibe 4.

Some scoring machines calculate with a 4.6 mm gauge, the SAM 4000 for example, and then every limit sits 5 Teiler further out than in the calculator at 4.5 mm. What that means when you compare two systems is covered in Teiler and ring score.

Frequently asked questions

Which projectile diameter do I enter?

4.5 mm for air rifle and air pistol, and for a .22 on 50 m smallbore or Scheibe 4 it is 5.6 mm. Both are prefilled. For a 7.8 mm centerfire standard rifle on Scheibe 4 you change the field, and the ten then ends at 2,890 Teiler, with 5.6 mm at 2,780. Other calibers go in the same way.

Why does my range print a different tenth than the calculator?

The SAM 4000, for example, calculates with a 4.6 mm gauge, which puts every limit 5 Teiler further out: a 129.2 Teiler is a 10.5 there and a 10.4 at 4.5 mm. The measured distance is the same in both cases, the two systems draw the limit in different places.

Can I compare pistol and rifle with the calculator?

Yes, through the Teiler factor field, if your match rules set one. The DSB Sportordnung, the German federation’s rulebook, contains no such factor, it comes from the match announcement. For supported shooting against freehand, clubs often multiply by about 1.5. Ring Reader stores the raw Teiler and applies no factor. If you want to compete across disciplines inside the app, use the “Decimal digits” mode under “Challenges”, where only the tenths count.
