If you are new to strength training, you may look at a barbell in the gym and wonder, “How heavy is this bar?”
It is an important question because the barbell itself adds weight to your exercise. You cannot calculate your total lifting weight by counting only the plates.
A barbell can have different weights depending on its type, size, design, and purpose.
A common Olympic barbell used in many gyms weighs about 20 kg (44 lb). However, some barbells are lighter, while specialty bars can be much heavier.
Understanding barbell weight can help you track your workouts, choose the right equipment, and avoid mistakes when calculating how much you are lifting.
How Heavy Is a Normal Barbell?
A typical Olympic barbell weighs approximately 20 kg (44 lb).
This is probably the number you will encounter most often in a regular gym.
A standard Olympic bar is usually around 7 feet long and has sleeves on both ends where weight plates are loaded.
It is commonly used for exercises such as:
- Bench press
- Squats
- Deadlifts
- Overhead press
- Barbell rows
- Lunges
- Front squats
If someone says they are lifting an empty Olympic bar, they are often referring to approximately 20 kg.
However, you should always check the bar because not every bar has the same weight.
How Heavy Is a 45-Pound Barbell?
A 45-pound barbell weighs approximately 20.4 kg.
The 45-pound bar is very common in gyms, particularly in countries where weight is measured in pounds.
People often refer to it simply as a “45-pound bar.”
A 45 lb bar is slightly heavier than a 20 kg bar, but the difference is small.
For general gym training, people may use the terms 20 kg bar and 45 lb bar almost interchangeably.
How Heavy Is a 20 kg Barbell?
A 20 kg barbell weighs about 44.1 pounds.
This is a common weight for men’s Olympic barbells.
When you are calculating your total lift, start with the weight of the bar.
For example, if you have a 20 kg bar and put 10 kg on each side:
20 + 10 + 10 = 40 kg
Your total lift is therefore 40 kg.
How Heavy Is a Women’s Barbell?
A common women’s Olympic barbell weighs approximately 15 kg (33 lb).
It is usually shorter and thinner than a standard 20 kg Olympic bar.
The smaller diameter can make the bar easier to grip, especially for people with smaller hands.
A 15 kg bar can be used for many of the same exercises as a standard Olympic bar.
These include:
- Squats
- Deadlifts
- Bench press
- Overhead press
- Cleans
- Snatches
The exact specifications can vary between manufacturers.
How Heavy Is a Beginner Barbell?
Beginner barbells are available in different weights.
Some lightweight training bars weigh around 5 kg, while others may weigh 10 kg or 15 kg.
These bars are useful for people who are learning lifting techniques.
For someone who is not comfortable with a 20 kg bar, a lighter training bar can be a good starting point.
A lighter bar also allows beginners to practice movements without immediately dealing with a heavy load.
There is no universal weight for a beginner bar, so check the manufacturer’s specifications.
How Heavy Is an EZ Curl Bar?
An EZ curl bar has a different shape from a normal straight barbell.
The angled grip sections allow you to hold the bar in different positions.
Many EZ curl bars weigh approximately 5–12 kg.
However, the exact weight depends on the model.
EZ bars are commonly used for:
- Biceps curls
- Reverse curls
- Triceps extensions
- Close-grip curls
Because EZ bars are generally shorter than Olympic bars, they are usually much lighter.
How Heavy Is a Trap Bar?
A trap bar, also known as a hex bar, is a specialty bar commonly used for deadlifts.
Many trap bars weigh around 20–30 kg, although some models can weigh more.
The shape of the trap bar allows you to stand inside the bar rather than behind it.
This creates a different lifting position compared with a traditional straight bar.
Trap bars are commonly used for:
- Deadlifts
- Shrugs
- Farmer’s carries
- Squats
- Strength training
Always check the specifications because trap bars vary considerably.
How Heavy Is a Safety Squat Bar?
A safety squat bar is designed specifically for squatting.
It usually has shoulder padding and handles that you can hold during the exercise.
Many safety squat bars weigh around 20–30 kg.
Some specialty models can be heavier.
Because the bar has extra construction, padding, and handles, you should not assume that it weighs the same as a standard Olympic bar.
How Heavy Is a Deadlift Bar?
A deadlift bar is designed specifically for deadlifting.
Many deadlift bars weigh approximately 20 kg (44 lb).
However, the specifications can vary.
Deadlift bars may have different lengths, flexibility, shaft diameters, and sleeve designs.
If you are tracking your deadlift accurately, check the exact specifications of your bar.
How Heavy Is a Powerlifting Bar?
A typical powerlifting bar weighs around 20 kg (44 lb).
Powerlifting bars are designed for the three major powerlifting exercises:
- Squat
- Bench press
- Deadlift
They are designed to handle heavy loads and are built with characteristics suited to strength training.
Not every powerlifting bar weighs exactly 20 kg, so checking the manufacturer’s information is still recommended.
How Heavy Is a Smith Machine Bar?
A Smith machine bar is different from a free-weight barbell.
The bar is attached to the machine and travels along fixed rails.
Many Smith machines also have counterbalance systems.
Because of this, the resistance you feel when moving the bar can be very different from the physical weight of the bar itself.
One Smith machine may feel much lighter than another.
There is therefore no universal Smith machine bar weight.
If you want to know the starting resistance of your machine, check its specifications or ask a gym trainer.
Barbell Weight Comparison
Here is a simple comparison of common bar types:
Bar Type Approximate Weight
Standard Olympic bar 20 kg / 44 lb
45 lb bar 45 lb / 20.4 kg
Women’s Olympic bar 15 kg / 33 lb
Beginner/training bar 5–15 kg
EZ curl bar 5–12 kg
Trap/hex bar 20–30 kg+
Safety squat bar 20–30 kg
Deadlift bar Around 20 kg
Powerlifting bar Around 20 kg
Smith machine bar Varies
These are general ranges.
The actual weight of a particular bar may be different.
Why Does Barbell Weight Matter?
Knowing how heavy your barbell is helps you understand how much weight you are actually lifting.
Imagine you put two 10 kg plates on a 20 kg bar.
It is easy to think you are lifting 20 kg because there are two 10 kg plates.
But the calculation is:
20 kg bar + 10 kg plate + 10 kg plate = 40 kg
You are lifting 40 kg in total.
This is why the bar must be included when recording your workout.
How to Calculate Your Total Barbell Weight
The calculation is simple.
Add the bar weight to the weight of all the plates.
Example 1: 5 kg Plates
Suppose you use:
- 20 kg bar
- 5 kg plate on the left
- 5 kg plate on the right
The total is:
20 + 5 + 5 = 30 kg
You are lifting 30 kg.
Example 2: 10 kg Plates
Now suppose you use a 20 kg bar with a 10 kg plate on each side.
20 + 10 + 10 = 40 kg
Your total is 40 kg.
Example 3: 20 kg Plates
With a 20 kg bar and a 20 kg plate on each side:
20 + 20 + 20 = 60 kg
Your total is 60 kg.
Why You Should Count Both Sides
One common mistake beginners make is counting only one side of the bar.
For example, if you put a 15 kg plate on each side, you have added:
15 + 15 = 30 kg
You have not added 15 kg.
Then you add the bar.
With a 20 kg bar:
20 + 30 = 50 kg
Your total lifting weight is 50 kg.
Does the Barbell Count as Weight?
Yes.
The barbell is part of the resistance.
If your bar weighs 20 kg and there are 40 kg of plates on it, your total is 60 kg.
This applies to most free-weight barbell exercises.
Keeping this in mind makes it easier to track your strength progression.
How Can You Find Out How Heavy Your Bar Is?
If you are unsure about your barbell’s weight, there are several ways to find out.
Look for Markings
Some bars have their weight printed or engraved on them.
Look near the center of the bar or around the sleeves.
Ask Gym Staff
If you are using equipment at a commercial gym, ask a trainer or staff member.
They may know the weight and specifications of each bar.
Check the brand and Model.
If you know the manufacturer and model, you can check its specifications.
This is particularly useful for specialty bars.
Weigh the Bar
You can also weigh the bar directly if you have access to a suitable scale.
This is useful when the bar does not have a visible weight marking.
Is a Heavier Bar Harder to Lift?
Yes, if all other factors are the same, a heavier bar contributes more resistance.
However, the difficulty of an exercise depends on more than the weight of the bar.
Your technique, range of motion, exercise selection, repetitions, and total load all matter.
A 20 kg bar with no plates may be harder for a beginner than a lighter bar.
That is why beginners should choose equipment that matches their current ability.
Does a Heavier Bar Mean a Better Bar?
No.
A heavier bar is not automatically better.
Different bars are designed for different purposes.
For example, a lightweight training bar can be excellent for learning technique.
An Olympic bar can be useful for general strength training.
An EZ curl bar is designed for certain arm exercises.
A trap bar can be useful for deadlift variations.
The best bar is the one that suits your exercise and training goals.
How Heavy Should a Barbell Be for Beginners?
There is no single beginner weight that works for everyone.
Some people can comfortably use a 20 kg bar.
Others may need a lighter bar to learn the movement safely.
If you are new to strength training, start with a weight that allows you to maintain good form.
Do not choose a heavy bar simply because other people in the gym are using one.
Strength develops gradually.
Barbell Weight for Bench Press
A common bench press bar weighs approximately 20 kg.
For example:
20 kg bar + 5 kg each side = 30 kg
With 10 kg on each side:
20 + 10 + 10 = 40 kg
With 15 kg on each side:
20 + 15 + 15 = 50 kg
This makes it easy to track your progress over time.
Barbell Weight for Squats
The same principle applies to squats.
A common Olympic bar weighs around 20 kg.
If you squat with an empty bar, you are already moving approximately 20 kg.
If you add 10 kg to each side:
20 + 10 + 10 = 40 kg
As your strength improves, you can gradually add more weight.
Barbell Weight for Deadlifts
A typical Olympic deadlift setup starts with a bar around 20 kg.
For example:
20 kg bar + 20 kg each side = 60 kg
If you use 25 kg on each side:
20 + 25 + 25 = 70 kg
Remember that a specialized deadlift bar may have a different weight.
Common Mistakes When Estimating Barbell Weight
One of the biggest mistakes is assuming that every barbell weighs 20 kg.
That is not true.
Another mistake is forgetting to count the plates on both sides.
People also sometimes assume that a Smith machine has the same starting weight as a free-weight Olympic bar.
It does not necessarily work that way.
Finally, some people forget that specialty bars can be significantly heavier or lighter than a standard bar.

Final Thoughts
So, how heavy is a barbell?
For a common Olympic barbell, the answer is usually around 20 kg (44 lb).
But barbells come in many different sizes and designs. A women’s Olympic bar may weigh around 15 kg, while an EZ curl bar can be much lighter. Trap bars and safety squat bars may be around 20–30 kg or more.
Knowing the weight of your bar is important because the bar is part of the total weight you are lifting.
When you track your workouts, remember this simple formula:
Bar weight + all plates = total lifting weight
Once you understand this calculation, it becomes much easier to track your strength, set realistic goals, and measure your progress from one workout to the next.
The most important thing is not how heavy your bar looks. Focus on using the right equipment, maintaining good form, and increasing the weight gradually as your strength improves.
