Box Lacrosse vs Field Lacrosse: The Key Differences
Box lacrosse and field lacrosse are two versions of the same sport, and the core difference is space: box lacrosse crams six players a side into an indoor hockey rink with the boards in play, while field lacrosse spreads ten players across 110 yards of open grass. That one change, from a walled box to a wide field, reshapes the goals, the sticks, the speed and the whole feel of the game.
If you're new to lacrosse, this is the first fork in the road. One sport, two personalities. So let's lay them side by side, the way a curious fan actually wants, and sort out which one you're watching.
And almost everything below traces back to that confined, walled arena. Call it the box effect.
Key takeaways
- Players: Box lacrosse is six a side (five runners and a goalie); men's field lacrosse is ten a side (three attack, three midfield, three defense and a goalie).
- The box effect: Box is played on a hockey rink (about 180–200 ft long) with the boards keeping the ball alive, so it's faster, tighter and more physical than the open field.
- Goals: Box goals are tiny at 4 by 4 feet; field goals are 6 by 6 feet, so box goalies wear far more padding and fill the net.
- Sticks and clock: Field allows long defensive poles up to 72 inches and gives offenses more time; box uses short sticks only and a strict 30-second shot clock.
- Where you'll see them: Box headlines the indoor NLL (a winter sport); field headlines the outdoor PLL and US college (a spring sport). The 2028 Olympics use a third format, Sixes.
What's the difference between box and field lacrosse?
Box and field lacrosse differ most in space and numbers. Box lacrosse is played six a side on an enclosed hockey rink with small 4-by-4-foot goals, a 30-second shot clock and heavy contact off the boards. Field lacrosse is played ten a side on a 110-by-60-yard outdoor field with larger 6-by-6-foot goals, long defensive poles and more open running.
Both are lacrosse: you carry, pass and shoot a ball with a netted stick, and you score in a goal. But box was built indoors, in Canadian arenas, to keep the game going through winter, and that walled space made it a different animal. The box effect is where it starts.
The box effect: walls, space and speed
A box lacrosse rink is roughly 180 to 200 feet long and 80 to 90 feet wide, the footprint of an ice hockey rink with the ice covered. The boards are in play, like hockey, so the ball rarely goes out and the action almost never stops. Cram six players into that, and you get a fast, claustrophobic game of quick passes, picks and bone-rattling checks.
Field lacrosse opens it all up. Ten players spread across a pitch the length of a football field, with sidelines and end lines that send the ball out of bounds and reset play. There's room to run, to clear the ball the length of the field, to use long-range defenders. Same stick, same ball, completely different rhythm. One is a phone booth brawl; the other is a track meet with sticks.
To the Haudenosaunee who created it, lacrosse is the Creator's Game, a medicine game played long before anyone drew lines for a field or built a box. — Haudenosaunee tradition
Players, goals and sticks
Count the bodies first. Men's field lacrosse fields ten a side: three attackmen, three midfielders, three defensemen and a goalkeeper, with an offside rule that keeps players honest about which half they're in. Box lacrosse runs six: five runners and a goalie, no offside, everyone defending and attacking in a tight rotation.
The goals tell the rest of the story. A field goal is a big 6-by-6-foot square. A box goal is a cramped 4 by 4 feet (the pro NLL nudges it to about 4 foot 9 wide). That's why a box goalie looks like a padded fortress, almost filling the net, while a field goalie has real corners to protect. Sticks differ too: field defenders carry long poles, 52 to 72 inches, to disrupt from distance, while box bans those long poles and sticks to shorter crosses for the tighter quarters.
Box lacrosse vs field lacrosse: the full comparison
| Feature | Box lacrosse | Field lacrosse (men's) |
|---|---|---|
| Players per side | 6 (5 runners + goalie) | 10 (3 att / 3 mid / 3 def / GK) |
| Playing area | Hockey rink, ~180–200 ft long | 110 × 60 yd outdoor field |
| Boards / out of bounds | Boards in play (ball stays live) | Sidelines and end lines (ball goes out) |
| Goal size | 4 × 4 ft (NLL ~4'9" wide) | 6 × 6 ft |
| Shot clock | 30 seconds | ~80 seconds (NCAA men's) |
| Sticks | Short crosses only | Short + long poles (52–72 in) |
| Offside rule | No | Yes |
| Top pro league | NLL (indoor) | PLL (outdoor) |
| Typical season | Winter (indoor) | Spring/summer (outdoor) |
Physicality and style
Box is the rougher ride. With the boards right there and only six players in a small space, defenders lean on cross-checks and body checks, and offenses answer with quick give-and-go passing and screens borrowed straight from hockey. It rewards toughness and fast hands in traffic.
Field rewards different things: endurance, field vision, dodging in space and long-range defending. A field defenseman with a 6-foot pole can break up a play from yards away, something impossible in the box. Neither is "better." They build different players, which is exactly why so many elite athletes grow up playing both.
Where you'll watch each, and the Olympic twist
Box lacrosse's big stage is the National Lacrosse League, an indoor winter league across North America. Field lacrosse's pro home is the outdoor Premier Lacrosse League, alongside the huge US college (NCAA) scene each spring. You can follow both through our lacrosse hub.
Here's the timely wrinkle: when lacrosse returns to the Olympics at LA 2028, it won't be box or full field. It'll be Sixes, a six-a-side outdoor format World Lacrosse built for a global audience, borrowing the small numbers of box and the open grass of field. You can read more in our guide to the 2028 LA Olympics.
The bottom line: it's all about the box effect
Box and field lacrosse share a stick, a ball and a name, and split on almost everything else, and the split starts with the box. Wall the game in and shrink the numbers, and you get the fast, physical six-a-side box game with its tiny goals and 30-second clock. Open it up to ten players on 110 yards of grass, and you get the running, dodging, long-pole field game. New to the sport?

Frequently asked questions
What is the main difference between box and field lacrosse?
Space and numbers. Box lacrosse is six a side on an enclosed indoor hockey rink with the boards in play, small 4-by-4-foot goals and a 30-second shot clock. Field lacrosse is ten a side on a 110-by-60-yard outdoor field with 6-by-6-foot goals and more open running.
How many players are on a box lacrosse team versus field lacrosse?
Box lacrosse has six players on the floor per side: five runners and a goalie. Men's field lacrosse has ten per side: three attackmen, three midfielders, three defensemen and a goalkeeper.
Why are box lacrosse goals smaller?
Box goals are 4 by 4 feet, against 6 by 6 feet in field lacrosse. The smaller net suits the tighter, faster indoor game, which is also why box goalies wear much bulkier padding and seem to fill the entire goal.
Is box lacrosse more physical than field lacrosse?
Generally, yes. With the boards in play and only six players in a small rink, box lacrosse features constant contact, cross-checking and hockey-style screens, and the ball almost never stops. Field lacrosse is physical too, but its open space puts more weight on running and long-range defending.
Which lacrosse is in the 2028 Olympics?
Neither box nor traditional field. The Los Angeles 2028 Games will use Sixes, a six-a-side outdoor format created by World Lacrosse that blends the small rosters of box with the open field of the outdoor game, designed to be faster and easier for new fans to follow.
Do players play both box and field lacrosse?
Many do. Lots of elite players, especially in Canada, grow up on box in winter and field in spring. Box is widely credited with sharpening stick skills and toughness in traffic, which then translate to the open field.
