Netting mesh size chart by sport: official ball sizes, published mesh recommendations

A net contains a ball when its mesh is smaller than the ball: that single rule, applied to the official ball dimensions each sport publishes in its rulebook, explains every mesh size on the market, from 19 mm golf impact netting to 120 mm football ball stop. This page puts the two halves side by side: the exact ball sizes from 11 federation rules (linked), and the mesh sizes netting sellers actually publish, including where they disagree. Conversions between US inches and UK millimetres are shown throughout.

How do you choose a mesh size for sports netting?

Start from the ball, then the use. The mesh must be comfortably smaller than the smallest ball involved: a 42.67 mm golf ball passes a 44.45 mm baseball mesh by dimension alone. Then distinguish impact netting (the ball strikes the net at speed, at close range: cages, bays, backstops), where sellers specify tighter mesh and heavier twine, from barrier netting (perimeter containment at distance), where a larger mesh is published as acceptable: West Coast Netting's FAQ lists 1 in mesh for golf barriers while recommending 7/8 in for impact. Finally, mesh size and twine gauge are independent choices: the first decides what gets through, the second how hard and how often it can be hit.

Official ball sizes by sport, from the federation rulebooks

Every value below is quoted from the current rule of the sport's governing body, linked. Where the rule gives a circumference, the diameter is our arithmetic conversion (circumference divided by π), marked "calculated". Sorted smallest to largest: the smaller the ball, the tighter the mesh must be.

Data note: a 749 to 780 mm figure for the FIBA size 7 basketball still circulates online; the FIBA Official Basketball Rules 2024 equipment table, read directly, says 750 to 770 mm. Women's and junior cricket balls are smaller than the men's ball quoted above (MCC Law 4.6).

Published mesh recommendations by sport (and where sellers disagree)

These are the mesh sizes netting sellers publish for each application, credited by name. They are seller recommendations, not federation rules: no governing body we reviewed mandates a netting mesh size. Where publications disagree, every figure is shown.

Two patterns worth noting in the disagreements. First, the golf impact range (3/4 in vs 7/8 in vs 20 vs 22 mm) spans barely 3 mm: all four contain the 42.67 mm ball with a wide margin, so the choice is driven by twine, price and availability rather than physics. Second, the cricket gap is real: 48 mm lane netting (Net World Sports) versus Huck's 20 to 30 mm for perimeter ball stop reflects impact versus boundary use, not a contradiction.

What mesh size stops a golf ball?

Anything meaningfully under 42.67 mm, the minimum diameter in the R&A/USGA Equipment Rules. In practice the published impact meshes are 3/4 in (19.05 mm), 7/8 in (22.23 mm) and 20 to 22 mm in the UK; 1 in (25.4 mm) is published for distant barriers only. The tighter the mesh, the more twine per square metre: golf netting is priced and weighed accordingly, which is why nobody specs golf mesh for sports that do not need it.

Can a golf ball go through baseball netting?

By the numbers, almost: standard 1-3/4 in baseball mesh is 44.45 mm, a golf ball is 42.67 mm minimum, a clearance under 2 mm, and at speed the mesh deforms. Practice Sports answers this exact question in its Playbook and recommends, for a dual-purpose cage, ordering golf-size mesh with a baseball-grade #36 twine rather than reusing a baseball net for golf. If you are specifying one net for two sports, size the mesh for the smaller ball and the twine for the harder impact.

Mesh size conversion: inches to millimetres

US sellers publish mesh in inches, UK and European sellers in millimetres, and almost nobody shows both. The conversions below are exact arithmetic (1 in = 25.4 mm):

What our own catalogue documents

Our manufacturing partner specifies everything in millimetres: mesh from 10 mm to 100 mm and twine from 1 mm to 6 mm, in polyester, verified against factory samples, which maps cleanly onto the applications above (20 mm range for golf and racket sports, 45 mm for baseball-type containment, 100 mm for football and rugby ball stop). Browse the netting families, or use theSpec Finder to see which documented mesh and twine combinations fit your application; every spec is confirmed in writing before anything ships.

How we compiled this chart

Ball dimensions were taken from the current published rules of each governing body (July 2026), quoted as written and linked in the table; where a rule specifies a circumference we calculated the diameter and marked it as a calculation. Mesh recommendations were collected from the public pages of named netting sellers and are credited inline; sellers who compete with us are named but not linked. Nothing on this page is averaged across sources, and disagreements are shown rather than resolved.
