Learn the football throw-in: legal stance, throwing arc, accurate delivery and the offside edge – with milestones and an honest look at the evidence.
The honest answer up front: A throw-in is valid when you face the field, keep part of each foot on or behind the touchline and throw the ball with both hands from behind and over your head [1]. Sounds trivial. Yet in amateur football the ball goes to the opponent all the time because a foot lifts or one arm does all the work.
And the throw-in is more than "getting the ball back in". In an analysis of 3,457 Bundesliga goals, "goal after throw-in" appeared as its own recognisable pattern [2]. In the German children's game formats, by contrast, it only exists in seven-a-side; smaller formats restart by dribbling or passing in [3]. So many players learn the throw-in late. Learn it before it matters.
Stand at the line facing the field. Part of each foot must stay on the line or on the ground behind it while the ball leaves your hands. You throw with both hands, from behind and over the head, from the spot where the ball left the field [1]. Opponents must stand at least 2 m away [1] – about a step and a half.
Milestone: 10 out of 10 throws in a row from a legal stance, checked on phone video.
Take the ball behind your head, open your elbows and lean the upper body slightly back, as if drawing a bow. Then the trunk snaps forward and the arms follow. The power comes from the whole body, not from the forearms. This technique description is practical experience, not a study finding.
Milestone: 10 throws from 10 m, at least 7 land in a 2 m square.
For long throws people often say "45 degrees". A study of a single male player throwing between 10 and 60 degrees found something else: at low angles he released the ball faster, and his best angle was around 30 degrees – flatter than your gut says [4]. That is a hint, not a law: body structure matters.
Milestone: Try 5 throws each at flat, medium and steep and write down which flies furthest.
A throw-in should arrive, not just fly. In a DFB drill the thrower aims at the team-mate's chest, thigh or foot, and the receiver controls and passes on directly [5].
Milestone: 8 out of 10 throws that your partner can control with one touch.
Throw, move straight into free space and offer yourself. But careful: you may not touch the ball again before another player has played it [1].
Milestone: In a 3-v-1 situation, 5 throw-ins in a row that keep the ball safely with your team.
The throw-in loads shoulders and lower back more than it looks. Warm up with a programme like FIFA 11+: in a meta-analysis it cut the injury rate by 39% [6]. Do not throw to your own goalkeeper, who may not pick the ball up with the hands when it comes directly from a throw-in by their own team – that gives an indirect free kick [7]. This guide explains and motivates; it does not replace supervised training.
The throw-in is your chance to switch off offside: a player who receives the ball directly from a throw-in cannot be offside [8]. So throw quickly and early, before the opponent organises, and look for the team-mate who can start behind the line.
No. While you release the ball, part of each foot must stay on or behind the touchline, on the ground. If a foot lifts, the throw-in is not taken correctly and goes to the opponent [1].
No. If the ball goes straight into the opponents' goal, a goal kick is awarded to them. If it goes into your own goal, a corner kick is awarded to them [1].
At least 2 m from the spot on the touchline where the throw is taken [1]. That is about a step and a half.
Not automatically 45 degrees. In a study with a single player the best release angle was about 30 degrees, because he could throw faster at a flatter angle [4]. Test what works best for your own body.
It is allowed but risky: the goalkeeper may not handle the ball when receiving it directly from a throw-in by their own team. If they do, an indirect free kick is awarded [7].
