Look at a club noticeboard after a match and you will find the same conversation every time: somebody squinting at a target card, finger hovering over a ragged hole, asking whether that shot touched the line for the higher value. The scoring zones settle it. Every ISSF target is a map of concentric rings, each one a scoring zone, and once you understand how the zones are drawn, sized, and subdivided, reading a card stops being guesswork.
This guide walks through the ring layout shared by all ISSF targets, the exact dimensions for the common events, and the decimal scoring that decides finals by tenths.
How ISSF Target Scoring Zones Are Built
Every ISSF target, from the tiny air rifle card to the 500 mm 25 m precision target, follows the same construction logic. Ten concentric rings carry values from 1 at the outside to 10 at the center. Rings are drawn in contrasting zones, usually white outer rings and a black aiming area covering the inner rings, though how far the black extends varies: down to the 4 ring on the air rifle card, the 7 ring on air pistol, the 3 ring zone on 50 m rifle, and the 7 ring on 25 m precision targets.
One measurement rule trips up almost every new shooter: the ISSF measures all ring dimensions as outside diameters, edge to edge. When the rulebook says the air rifle 10 ring is 0.5 mm, that means 0.5 mm from one outer edge of the ring to the other, not a 0.5 mm radius or line width. The same convention applies to every ring on every target, which is why scoring gauges are built the way they are; we cover that connection below.
A shot earns the value of the highest ring it touches or breaks. A hole that clips the outer edge of the 9 ring, even by a whisker of torn paper, scores 9, not 8. That single rule explains most of the squinting at the noticeboard, and it is also why close calls get measured rather than argued.
Where the inner ten fits
Several targets also carry an inner ten, a smaller circle inside the 10 ring. On paper scoring it exists mainly for tiebreaking: two shooters level on total can be separated by their count of inner tens. The classic example is the air pistol target, where the inner ten is a 5 mm circle and the visible 10 ring itself is the 11.5 mm black center you aim at. Under decimal scoring the inner ten largely disappears as a separate concept, because tenths do the same job with finer resolution.
Ring Dimensions for the Common ISSF Targets
Ring sizes are not arbitrary. They scale with distance and the inherent precision of the equipment, which is why comparing targets across events is so revealing. The air rifle 10 ring is a dot half a millimeter across, while the 50 m pistol 10 ring is 50 mm across, a hundred times wider.
| Target | 10 ring | Inner ten | Black area | Full target (1 ring) |
|---|---|---|---|---|
| 10 m Air Rifle | 0.5 mm | 0.5 mm (dot is the 10) | 30.5 mm (4 to 9 rings) | 45.5 mm |
| 10 m Air Pistol | 11.5 mm | 5.0 mm | 59.5 mm (7 to 10 rings) | 155.5 mm |
| 50 m Rifle | 10.4 mm | 5.0 mm | 112.4 mm (4 to 10 rings) | 154.4 mm |
| 25 m Precision / 50 m Pistol | 50 mm | 25 mm | 200 mm (7 to 10 rings) | 500 mm |
| 25 m Rapid Fire | 100 mm | none | 420 mm (6 to 10 rings) | 500 mm |
Tolerances are tight on the inner rings, around ±0.1 mm for the 10 m cards, which is why competition targets are printed rather than photocopied and why range officers replace faded cards. The full ring ladders step outward evenly: the air rifle rings are 5 mm apart, air pistol rings 16 mm apart, and the 25 m precision rings a generous 50 mm apart. For the complete table, including the 300 m targets and how each printed dimension decides close shots, see the ISSF target dimensions reference.
A quick sanity check on those numbers using air rifle: 1 ring 45.5 mm, 4 ring 30.5 mm (also the black edge), 9 ring 5.5 mm, 10 ring 0.5 mm. Each step inward removes 5 mm of diameter, straight down to the half-millimeter dot at the center.
What Is Decimal Scoring and Which Events Use It?
Decimal scoring divides the scoring area of one full ring into ten equal zones, valued in tenths. Inside the 10 ring, shots are scored 10.0 up to 10.9; inside the 9 ring, 9.0 up to 9.9, and so on. A 10.9 sits effectively in the center of the target; a 10.0 just barely broke into the ten zone from the 9 ring side.
It is used in the events where scoring resolution actually changes rankings: 10 m air rifle, 10 m air pistol, and 50 m rifle, in qualification and especially in finals. The 25 m pistol events and 50 m pistol stay with whole-ring scoring on paper, with inner tens for ties. If you want the full picture of how totals and finals differ event by event, our overview of how ISSF scoring works breaks down shot counts and formats alongside the zones themselves.
Decimal scores change how you read a card psychologically, too. A whole-ring 10 is anonymous; a 10.2 tells you the shot drifted low-left of center, and a string of 10.1s is an early warning that your hold is degrading before the nines ever appear. That feedback is why serious shooters log decimal values after training, not just daily totals.
How Ring Layout Affects Your Shooting
The zones are not just for the scoring table; they are aiming references. The black aiming area on each target is sized for the sights used at that distance, and knowing your ring scale in angular terms tells you what your wobble zone actually covers.
Consider the air rifle shooter. At 10 m, the whole 45.5 mm card subtends a small angle, and the 10 ring is a speck no iron sight can resolve, which is why air rifle shooters aim at the black blob and let the pellet's natural dispersion do the rest. Half a millimeter of movement at the target is roughly a tenth of a point; a wobble that wanders 3 mm across the black can swallow most of a ring. The pistol shooter at the same distance faces an 11.5 mm ten that is genuinely visible, so aim-off and hold refinement pay off differently. Reading your shot groups against the ring scale, rather than just totalling them, is the core skill in learning to read your target and fix grouping problems.
Distance tells the same story at the other end. The 50 m rifle 10 ring is 10.4 mm, twenty times wider than the air rifle's, yet it is brutally hard to hit because 50 m of wind, light, and position wobble stand between you and the target. The 25 m precision 10 ring, 50 mm across, looks enormous until you are shooting one-handed at a timer.
How Close Shots Are Measured Against the Zones
Paper scoring does not trust eyeballs for edge cases. Range officers use scoring gauges, plugs matched to the ring dimensions of each specific target, inserted into the hole to determine whether the higher ring was touched. Because ring sizes differ per event, so do the gauges; an air rifle gauge has nothing in common with a 25 m precision gauge. Our guide to how shot gauges and plug scoring work walks through the procedure and the outward-gauge quirk used for air rifle's inner ten.
Electronic targets take a different route: they compute the shot's center position and report a decimal value directly, accurate to half a decimal ring, with no plug in sight. The comparison of electronic targets versus paper explains what changes for you as a shooter when the range goes digital, including the fact that you stop seeing physical holes at all. One edge case electronic systems actually handle better is the crossfire: paper cards sometimes reveal a neighbour’s shot only at scoring, while a digital lane flags it immediately. Crossfire rules explains what happens to the shot and your score either way.
Either way, the underlying geometry is the ring ladder described above. Understand the zones and both scoring worlds become transparent.
Practicing Zone Awareness Without a Range
You do not need a match to train your eye on the zones. Photograph your training cards with TargetLog, a paper target scoring app built for ISSF targets, and it maps each hole to the correct ring layout for your event, including decimal values. Doing this after every session builds the habit of thinking in zones: which ring did that shot clip, what does the pattern across the zones say about your hold, did the group drift as the session went on.
Over weeks, that record turns into a picture of where your shots live inside the scoring zones, and that picture is what tells you whether the next training block should chase the center or first fix the outliers dropping into the 8 zone.
FAQ
Does a shot score by where the hole's center is?
On paper, no. The shot gets the value of the highest ring it touches or breaks, judged by the edge of the hole, which is why a hole centered in the 8 zone but tearing into the 9 ring scores 9. Decimal scoring on electronic targets is closer to center-based, since the system computes the shot location and assigns tenths within whichever ring it lands.
Are ring sizes the same for juniors and qualifying events?
Yes. The official ISSF target specifications apply regardless of category; a junior air rifle match uses the same 45.5 mm card with the 0.5 mm ten as the Olympic final. What changes between matches is the format and shot count, not the zones.
Which ring is the hardest to see and aim at?
The air rifle 10 ring, a 0.5 mm white dot inside the black, is effectively invisible at 10 m with iron sights, so nobody aims at it directly. Shooters aim at the black area as a whole; the decimal scoring system then grades the results with tenths.
