If you are starting weightlifting or regularly working out at the gym, you may have wondered, how much does a barbell weigh?
It sounds like a simple question, but there is not one answer for every barbell.
Different barbells are made for different exercises. Some are designed for general strength training, while others are made for Olympic weightlifting, powerlifting, deadlifts, curls, or squats.
The weight can also change depending on the length, size, construction, and manufacturer.
For most people, the most important number to remember is that a standard Olympic barbell commonly weighs about 20 kg (44 lb).
However, there are many other types of bars that weigh less or more.
In this guide, we will explain the different types of barbells, their approximate weights, and how to calculate the total weight you are lifting.
How Much Does a Standard Barbell Weigh?
A typical Olympic barbell used in gyms weighs approximately 20 kg (44 lb).
This is one of the most common bars you will see in a commercial gym.
A standard Olympic bar is generally around 7 feet long and has rotating sleeves on both ends for Olympic weight plates.
It can be used for many exercises, including:
- Bench press
- Squats
- Deadlifts
- Overhead press
- Barbell rows
- Lunges
- Front squats
If your gym simply refers to a bar as an “Olympic bar,” it is often around 20 kg, but you should check the bar’s specifications if exact weight matters.
Is a 20 kg Barbell the Same as a 45 lb Bar?
They are very close, but they are not exactly the same.
A 20 kg bar weighs approximately 44.1 pounds.
A 45-pound bar weighs approximately 20.4 kg.
In many gyms, people use the terms “20 kg bar” and “45 lb bar” almost interchangeably because the difference is relatively small.
For normal training, this difference may not be important.
For competition lifting or very accurate strength tracking, however, it is better to know the exact weight of your bar.
How Much Does a Women’s Barbell Weigh?
A common women’s Olympic barbell weighs approximately 15 kg (33 lb).
It is usually shorter and has a smaller diameter than a typical 20 kg Olympic bar.
The smaller diameter can make the bar easier to grip for people with smaller hands.
Women’s Olympic bars are commonly used for:
- Squats
- Deadlifts
- Bench press
- Snatches
- Clean and jerks
- Overhead presses
The important thing to remember is that a women’s bar is not simply a normal bar with some weight removed. It has different dimensions and specifications.
How Much Does a Beginner Barbell Weigh?
Beginner and training barbells are available in many different weights.
Some lightweight bars weigh around 5 kg, while others may weigh 10 kg, 12 kg, or 15 kg.
These bars can be useful for people who are learning proper lifting technique.
They are also helpful for beginners who are not yet comfortable handling a 20 kg bar.
A lighter bar can allow you to practice movements without immediately having to manage a heavier load.
Always check the specifications of the particular bar because there is no universal weight for every beginner bar.
How Much Does an EZ Curl Bar Weigh?
An EZ curl bar is different from a straight Olympic bar.
It has angled sections that allow you to hold the bar in different positions.
This design is popular for exercises such as:
- Biceps curls
- Reverse curls
- Triceps extensions
- Close-grip curls
Many EZ curl bars weigh approximately 5–12 kg, although the exact weight depends on the model.
Some commercial EZ bars can be heavier.
If you are tracking your workout accurately, check the manufacturer’s specifications instead of assuming the bar weighs a certain amount.
How Much Does a Trap Bar Weigh?
A trap bar, also known as a hex bar, is a specialty bar commonly used for deadlifts.
Unlike a straight barbell, you stand inside the trap bar while lifting.
Many trap bars weigh approximately 20–30 kg, although some models can be lighter or significantly heavier.
Trap bars are popular because they allow you to keep the weight closer to your body during the movement.
They can be used for:
- Trap bar deadlifts
- Shrugs
- Farmer’s carries
- Squats
- Other strength exercises
Because trap bars have different designs, their weights can vary considerably.
How Much Does a Safety Squat Bar Weigh?
A safety squat bar is designed to make squatting more comfortable for some lifters.
It usually has padding around the shoulders and handles that you can hold during the exercise.
Many safety squat bars weigh around 20–30 kg, although the exact weight varies.
Some specialty models are heavier.
The additional padding, handles, and construction make the safety squat bar different from a normal Olympic bar.
How Much Does a Deadlift Bar Weigh?
A deadlift bar is specially designed for deadlifting.
It may be slightly longer or more flexible than some standard power bars.
Many deadlift bars weigh around 20 kg (44 lb).
However, you should not assume that every deadlift bar weighs exactly 20 kg.
Different manufacturers produce different models.
If you are trying to calculate your exact deadlift, check the specifications of the bar you are using.
How Much Does a Powerlifting Bar Weigh?
A typical powerlifting bar weighs around 20 kg (44 lb).
Powerlifting bars are designed primarily for:
- Squats
- Bench press
- Deadlifts
They are generally built to handle heavy loads.
Although many powerlifting bars weigh 20 kg, specialty bars may have different weights.
This is why checking the manufacturer’s information is useful when accuracy is important.
How Much Does a Smith Machine Bar Weigh?
A Smith machine is different from a free-weight barbell.
The bar is connected to rails and moves along a fixed path.
Many Smith machines also use a counterbalance system.
Because of this, the amount of resistance you feel can be very different from the actual physical weight of the bar.
For example, one Smith machine may feel relatively light when empty, while another may feel considerably heavier.
There is no universal Smith machine bar weight.
If you want to know how much resistance you are actually starting with, check the machine’s specifications or ask gym staff.
Barbell Weight Chart
Here is a simple reference chart:
| Type of Barbell | Approximate Weight |
|---|---|
| Standard Olympic bar | 20 kg / 44 lb |
| 45 lb Olympic 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 numbers are general guidelines.
The actual weight can be different depending on the manufacturer and model.
How Do You Calculate the Total Weight?
Calculating your total barbell weight is very simple.
Add the weight of the bar to the weight of all the plates.
For example, suppose you have:
20 kg bar + 10 kg plate on each side
The calculation is:
20 + 10 + 10 = 40 kg
So your total lifting weight is 40 kg.
The bar itself contributes 20 kg to the total.
Example With 20 kg Plates
Imagine you are doing squats with a 20 kg Olympic bar.
You place a 20 kg plate on each side.
The calculation is:
20 kg bar + 20 kg plate + 20 kg plate = 60 kg
You are therefore lifting 60 kg.
This is an important point for beginners because some people only count the weight of the plates.
Example With Different Plates
Suppose you use a 20 kg bar and put a 15 kg plate and a 5 kg plate on each side.
Each side contains:
15 + 5 = 20 kg
Both sides contain:
20 + 20 = 40 kg
Then add the bar:
40 + 20 = 60 kg
Your total weight is 60 kg.
Do Barbell Collars Count Toward the Weight?
Barbell collars or clips can add a small amount of weight.
For most casual gym workouts, people do not include them when recording their lifts.
However, in competitive lifting, every part of the equipment can matter.
If you need an exact total, you can include the weight of the collars as well.
Why Is Knowing Barbell Weight Important?
Knowing the weight of your bar helps you track your progress.
Imagine you bench press with a bar that weighs 20 kg.
You put 10 kg on each side.
Your total is 40 kg.
If you later move to 15 kg on each side, your total becomes:
20 + 15 + 15 = 50 kg
You have increased your total weight by 10 kg.
Without counting the bar, you could easily record the workout incorrectly.
How Can You Find the Exact Weight of Your Barbell?
There are several ways to find the exact weight.
Check the Bar
Some barbells have their weight printed or engraved on them.
Look near the center or sleeves of the bar.
Check the Manufacturer
If you know the brand and model, look at the manufacturer’s specifications.
This is one of the best ways to find accurate information.
Ask Your Gym
If you are training at a commercial gym, ask a trainer or staff member.
They may know which bars are 15 kg, 20 kg, or another weight.
Weigh the Bar
You can also weigh the bar directly if you have a suitable scale.
This is particularly useful for bars without markings.
Why Don’t All Barbells Weigh the Same?
Barbells are made for different purposes.
A competition Olympic bar is designed differently from an EZ curl bar.
A safety squat bar has padding and handles.
A trap bar has a completely different shape.
A beginner bar is designed to be lighter.
Because of these differences, there is no single weight that applies to every barbell.
Does a Heavier Barbell Mean a Better Barbell?
Not necessarily.
A heavier bar is not automatically a better bar.
The best bar depends on what you want to do with it.
For example, a 20 kg Olympic bar may be excellent for general strength training.
An EZ curl bar may be more useful for biceps exercises.
A trap bar may be a good choice for certain deadlift variations.
A safety squat bar can be useful for specific squat training.
The design and purpose of the bar matter more than simply how heavy it is.
What Barbell Weight Should Beginners Use?
Beginners should focus on learning proper technique before trying to lift very heavy weights.
For some exercises, an empty 20 kg bar may be appropriate.
For others, a lighter training bar may be better.
The right starting weight is one that allows you to perform your exercises with good control and proper form.
You should not feel pressured to use the heaviest bar or the heaviest plates in the gym.
Barbell Weight for Bench Press
The bench press is commonly performed with a 20 kg Olympic or powerlifting bar.
For example:
20 kg bar + 5 kg on each side = 30 kg total
If you use 10 kg on each side:
20 + 10 + 10 = 40 kg
If you use 20 kg on each side:
20 + 20 + 20 = 60 kg
Always check which bar you are using because the starting weight can be different.
Barbell Weight for Squats
A standard Olympic bar commonly weighs around 20 kg.
A beginner might start with the empty bar to learn the squat movement.
Once comfortable, plates can be added gradually.
For example:
20 kg bar + 5 kg each side = 30 kg
Then:
20 kg bar + 10 kg each side = 40 kg
The goal should be gradual progress while maintaining proper form.
Barbell Weight for Deadlifts
Deadlifts are often performed with a 20 kg Olympic bar or a dedicated deadlift bar.
For example:
20 kg bar + 15 kg each side = 50 kg
If you put 20 kg on each side:
20 + 20 + 20 = 60 kg
If you use 25 kg on each side:
20 + 25 + 25 = 70 kg
The exact starting weight should depend on your training experience and ability.
How Barbell Weight Affects Your Workout
Even the empty bar provides resistance.
For someone who is new to weightlifting, a 20 kg bar can already feel challenging.
As you become stronger, you can gradually add plates.
This is one of the simplest ways to use progressive overload.
You do not have to add large amounts of weight at once.
Small increases can make a meaningful difference over time.
Common Mistakes When Counting Barbell Weight
One common mistake is assuming every bar weighs 20 kg.
That is not correct.
Another mistake is counting only one side of the plates.
For example, two 10 kg plates mean 20 kg of plates, not 10 kg.
A third mistake is forgetting that different machines and specialty bars can have different starting weights.
Always check the equipment before recording your workout.

Final Thoughts
So, how much does a barbell weigh?
For the most common Olympic barbell, the answer is approximately 20 kg (44 lb).
But that is not true for every bar.
Women’s bars are commonly around 15 kg, while beginner bars can be lighter. EZ curl bars, trap bars, safety squat bars, and other specialty bars can have completely different weights.
Understanding your barbell’s weight makes it easier to calculate your total lifting weight and track your progress.
Before starting a workout, take a moment to identify the bar you are using.
Once you know the bar’s weight, simply add the plates on both sides to calculate your total.
Most importantly, focus on good technique, controlled movements, and gradual progress. You do not need to lift extremely heavy weights to make progress. Consistent training and proper form are much more important for long-term strength and fitness.
