The Science of Hockey Stick Flex: What Flex Should You Use?
Share
If you’ve ever asked, “What hockey stick flex should I use?” — you’re not alone.
Hockey stick flex is one of the most misunderstood aspects of shooting performance. Parents often buy sticks that are too stiff. Players copy what the pros use without understanding why. And many young athletes struggle with shot power simply because they’re using the wrong flex.

Let’s break down the science.
What Is Hockey Stick Flex? (Hockey Stick Flex Explained)
Hockey stick flex refers to how much a stick bends when force is applied.
The flex number (like 40, 55, 75, 85, 100) represents how many pounds of force it takes to bend the stick one inch.
Example:
-
An 85 flex stick requires 85 pounds of pressure to bend it one inch.
The lower the flex number:
-
The easier the stick bends
-
The quicker the release
-
The more “whip” you feel
The higher the flex number:
-
The stiffer the stick
-
More control for strong players
-
Often preferred by heavier or more powerful shooters
Flex directly affects shot mechanics.
Why Stick Flex Matters More Than You Think
When you shoot, you’re not just swinging the stick.
You are loading the shaft.
The stick bends, stores energy, and then releases that energy into the puck.
This is called the “kick point” and “energy transfer.”
If the stick is too stiff:
-
It doesn’t bend enough
-
You lose shot power
-
Release feels slow
If the stick is too soft:
-
It over-flexes
-
Shots rise too high
-
You lose accuracy
The right flex maximizes power and control.
What Hockey Stick Flex Should I Use?
The general rule:
Stick flex should be about 50% of your body weight.
This is the most widely accepted starting point.
Example:
-
100 lb player → 50 flex stick
-
160 lb player → 80 flex stick
-
200 lb player → 100 flex stick
But this is only a guideline — not a strict rule.
Skill level, shooting style, and strength also matter.
Full Hockey Stick Flex Chart (By Weight & Age)
Here’s a practical stick flex chart families can use:
| Player Weight | Recommended Flex | Typical Age Range |
|---|---|---|
| 40–60 lbs | 20–30 flex | 5–7 years old |
| 60–80 lbs | 30–40 flex | 7–9 years old |
| 80–100 lbs | 40–50 flex | 9–11 years old |
| 100–120 lbs | 50–65 flex | 11–13 years old |
| 120–150 lbs | 65–75 flex | 13–15 years old |
| 150–180 lbs | 75–85 flex | 15–18 years old |
| 180–210 lbs | 85–100 flex | Junior / Adult |
| 210+ lbs | 100+ flex | Strong adult players |
This stick flex chart gives a strong starting point for most youth hockey players.

The most common mistake?
Buying sticks that are too stiff.
Many young players use:
-
65 flex when they should use 40–50
-
75 flex when they weigh 110 pounds
Why?
Because the stick “looks cool” or matches what older players use.
But improper flex limits development.
For youth players:
-
Lower flex = easier loading
-
Better mechanics
-
More confidence shooting
Proper flex helps kids learn how to shoot correctly.
The Half-Weight Rule (And When to Break It)
The “half your body weight” rule is solid — but not perfect.
Break it if:
1. Player Has Weak Upper Body Strength
Drop flex slightly below half body weight.
2. Player Has Explosive Mechanics
Stronger players may handle slightly stiffer sticks.
3. Player Takes Mostly Snap/Wrist Shots
Lower flex improves quick release.
4. Player Takes Heavy Slap Shots
May prefer slightly stiffer flex.
Modern hockey emphasizes quick release over booming slap shots — which is why lower flex sticks are becoming more common.
Cutting a Stick Changes Flex (Important!)
Here’s something many families don’t realize:
Cutting a hockey stick makes it stiffer.
For every inch you cut:
Flex increases by roughly 3–5 points.
Example:
-
75 flex stick cut down 3 inches → feels closer to 85–90 flex.
This is why youth players often accidentally use sticks that are too stiff.
If you buy a senior stick and cut it significantly, you’re increasing flex dramatically.
Always factor this into your decision.
Low Kick vs Mid Kick vs High Kick (Flex Profile Explained)
Flex isn’t just about stiffness — it’s also about where the stick bends.
Low Kick Point
-
Quick release
-
Ideal for snipers
-
Popular with modern players
Mid Kick Point
-
Balanced power
-
Good for all-around players
High Kick Point
-
Traditional power
-
More common in older stick models
Most youth and modern players benefit from low kick sticks due to faster release mechanics.
Does Lower Flex Mean More Shot Power?
This is where it gets interesting.
Many players assume:
Higher flex = harder shot.
That’s not always true.
If a player cannot properly load a stiff stick, they actually lose power.
A properly loaded lower flex stick often produces:
-
Faster release
-
More whip
-
Equal or greater velocity
NHL trends even show elite players dropping flex numbers in recent years.
Quick release is king in today’s game.
Common Stick Flex Mistakes
1. Buying Too Stiff “To Grow Into”
Just like skates — don’t do it.
2. Copying NHL Players
Pros have elite strength and technique.
3. Ignoring Height and Stick Length
Length adjustments impact flex.
4. Not Testing Flex Before Buying
Always try flexing stick in store if possible.
When Should You Move Up in Flex?
Increase flex when:
-
Player gains significant strength
-
Shots consistently over-flex stick
-
Player feels “whippy” instability
If shots constantly rise high and lose control, flex may be too low.
How Stick Flex Impacts Development
Correct stick flex:
-
Teaches proper shooting mechanics
-
Encourages weight transfer
-
Builds confidence
-
Improves puck velocity
Incorrect flex:
-
Causes poor habits
-
Reduces power
-
Leads to frustration
Flex is development-critical — especially in youth hockey.
Budget Considerations for Youth Hockey Sticks
Youth sticks range from:
-
$50–$100 (entry level)
-
$100–$200 (mid-tier)
-
$250–$350 (elite composite)
For younger players:
Mid-tier sticks often provide excellent performance without overpaying.
Competitive players who shoot frequently may benefit from higher-end models.
At Sandbar Hockey, we believe education matters just as much as equipment. Whether you’re playing in traditional hockey markets or growing the game in warmer climates, understanding hockey stick flex helps players maximize performance without wasting money.
Final Answer: What Hockey Stick Flex Should You Use?
Start here:
-
Divide body weight by 2
-
Consider strength and skill level
-
Factor in stick cutting
-
Prioritize mechanics over ego
If unsure, lean slightly lower rather than higher.
Most youth players benefit from more flex — not less.
Understanding hockey stick flex isn’t complicated once you break down the science.
The right stick flex helps players:
-
Shoot harder
-
Release quicker
-
Develop better mechanics
-
Build confidence
Choose wisely — because the wrong flex can hold back even the most talented player.
