How to Check a Box Goalie Stick’s Width Without Using the Wrong Rule
Under World Lacrosse rules, use the frame’s outside edges, with a 13-inch maximum—not the inside opening—and verify your competition’s code.
For a game governed by the 2026–2028 World Lacrosse Box Lacrosse Rules, a goalkeeper stick may be no more than 13 inches wide, measured from one outside edge of the frame to the opposite outside edge—approximately 33.0 cm. This is an international standard, not an automatic rule for every Canadian league, professional competition, age group, or tournament, so confirm the governing rules before deciding whether a stick is legal. (World Lacrosse rulebook)
The direct answer: 13 inches, outside edge to outside edge
The operative World Lacrosse measurement is outside-to-outside, not the open space inside the head. Place the measurement at one outside edge of the goalkeeper head’s frame and extend it to the opposite outside edge. Keep the result at or below 13 inches.
Here is a simplified illustration, not an official inspection protocol:

outside edge to outside edge
The distinction matters because the frame itself has thickness. Suppose a goalie head measures exactly 13 inches from the inside surface of one sidewall to the inside surface of the other. Adding the thickness of both sides could make the complete outside-to-outside span greater than 13 inches. An inside measurement therefore cannot establish compliance for a goalkeeper head.
The rule establishes the outside-edge basis, but it does not resolve every possible inspection detail. In particular, it should not be paraphrased as formally requiring measurement “at the widest point.” It also does not, on the supplied evidence, prescribe a particular measuring tool or explain how an official must handle every curved or asymmetric frame.
Do not use the runner-stick measurement method
World Lacrosse uses different width measurements for goalkeeper and non-goalkeeper heads. Applying the runner-stick method to a goalie head can produce a smaller, reassuring—but incorrect—reading.
| Equipment type | Measurement basis | Cited World Lacrosse limit |
|---|---|---|
| Goalkeeper head | Outside edge to outside edge | 13-inch maximum |
| Non-goalkeeper head | Inside measurement | 4.5–7 inches |
Frame thickness explains why the readings differ. The effect can be especially important with a thick, irregular, or handmade wooden frame: its open pocket area may fall within 13 inches even though the complete frame exceeds the goalkeeper limit.
Do not transfer specifications from field lacrosse, Sixes, runner sticks, retailer descriptions, or informal calculations to a box goalkeeper head. Those sources may address a different discipline, equipment category, ruleset, or set of measurement points. A community discussion about a proposed wooden goalie stick illustrates this potential confusion, but user-proposed dimensions and calculations are not verified specifications or proof that a finished stick is legal.
Check the other World Lacrosse dimensions at the same time
Width is only one part of the international equipment check. Under the cited World Lacrosse rules, the principal goalkeeper-stick dimensions are:
- Width: no more than 13 inches outside edge to outside edge (approximately 33.0 cm).
- Head length: no more than 16.5 inches from the top of the head to the bottom of the throat (approximately 41.9 cm).
- Complete-stick length: between 40 and 72 inches (approximately 101.6–182.9 cm).
All three dimensions are specified in the World Lacrosse box rulebook.
Passing the width check does not make the entire stick legal. A head can be narrow enough but too long, while a compliant head can still be attached to a complete stick that falls outside the permitted length range.
The applicable code may also regulate materials, construction, head attachment, and equipment condition. The World Lacrosse international code includes material and direct-head-attachment provisions, but those requirements should not automatically be transferred to Canadian domestic play when a national rule or event package provides a modification.
Which rulebook controls your stick?
The 13-inch outside-edge rule is a World Lacrosse international standard, not a universal rule for every box lacrosse competition. World Lacrosse states that its rules apply to its competitions, qualification events, and other international games it defines. National governing bodies may implement those rules according to their own timelines and adapt them for domestic needs.
Use this sequence before measuring:
- Identify the governing body for the league, tournament, or exhibition.
- Confirm the current rulebook and edition instead of relying on an old comparison sheet or a remembered rule.
- Check age, stage, or division modifications.
- Review the event technical package or tournament contract.
- Apply the measurement method prescribed by those documents.
For Canadian domestic play, the Lacrosse Canada equipment and rules memo for 2026 confirms that applicable measurements and event modifications still matter. The memo does not itself state a domestic goalkeeper-stick width or identify the points from which that width must be measured.
If the league rulebook and event package do not provide a clear answer, ask the event’s head official or equipment inspector. That is preferable to assuming either that the international rule automatically controls or that the domestic rule must be different.
Wooden and custom sticks require two separate checks
Lacrosse Canada’s 2026 guidance generally permits wooden sticks for players and goalkeepers unless an event technical package or tournament contract provides otherwise. That permission answers the material question; it does not waive the measurements that apply in the competition.
A wooden or custom stick therefore requires two core checks:
- Material legality: Is wood permitted for this competition, age group, and division?
- Dimensional legality: Does the stick satisfy the applicable width, head-length, and complete-length requirements?
Construction can be an additional ruleset-dependent issue. The governing documents may impose requirements concerning attachment, shape, components, or safe condition even when the material and dimensions are acceptable.
Do not treat online DIY measurements as approved specifications or construction instructions. Handmade frames may also present questions that the available rules do not conclusively answer, including whether particular coverings or protrusions affect the outside-edge reading and which procedure officials will use for a curved or asymmetric head. Those details should be resolved by the official responsible for the event rather than guessed in advance.
Before using a wooden or custom goalie stick:
- Retain the applicable rulebook and event package.
- Check every supported dimension, not just width.
- Review tournament, age-group, and division modifications.
- Request an official pre-use ruling for an irregular or handmade frame.
For a game governed by the 2026–2028 World Lacrosse box rules, the practical measurement is straightforward: check the goalkeeper head outside edge to outside edge and keep it at or below 13 inches. Then verify head length, complete-stick length, jurisdiction, and event modifications. Permission to use wood does not by itself establish full equipment compliance.
