Loading your barbell doesn't have to feel like a pop quiz in mental math. Today, I'm going to show you EXACTLY how to calculate barbell weights instantly (in both kg and lbs) using our free Barbell Calculator tool.
What is Barbell Weight?
Think of a barbell weight as your ticket to serious strength gains. But here's what most people don't realize: it's not just about the heavy plates you load on the ends.
Let's break this down into exactly what you need to know:
At its core, barbell weight is the total load you're lifting, which includes:
- The bar itself (more on this in a second)
- Weight plates loaded on each end
- Any clips or collars used to secure the weights
But here's where it gets interesting...

Weight Plate Guide
Let's face it - the weight room can sometimes feel like a puzzle when you're trying to load your barbell. Colour-coded plates, different materials, and a seemingly endless array of increments - where do you even start?
Fear not, my strength-seeking friend. In this section, we'll break down the anatomy of weight plates so you can load your barbell with confidence every time.
There are two primary types of weight plates you'll encounter in the gym:
Bumper Plates
- Made of dense rubber or urethane
- Designed for Olympic lifts and drops
- Available in 10lb, 15lb, 25lb, 35lb, 45lb sizes
- Ideal for home gyms and competition settings
Iron Plates
- Constructed from solid cast iron
- More affordable than bumper plates
- Sizes range from 2.5lb to 45lb
- Better for general strength training
- Can cause more damage if dropped
Both options have their advantages, so choose based on your workout needs and equipment availability.
Standard Barbell Plate Weight Increments
When it comes to weight plates, the most common increments you'll see are:
- 2.5 lbs / 1.25 kg
- 5 lbs / 2.5 kg
- 10 lbs / 5 kg
- 25 lbs / 10 kg
- 35 lbs / 15 kg
- 45 lbs / 20 kg
This allows you to load the barbell in small, precise steps as you progress in your training.
The Color Coding System
In the world of Olympic weightlifting, weight plates often follow a standardized color scheme:
- 10 lb / 5 kg: Blue
- 15 lb / 10 kg: Yellow
- 25 lb / 15 kg: Green
- 35 lb / 20 kg: Red
- 45 lb / 25 kg: Black
This visual cue makes it easy to quickly identify the right plates, especially during fast-paced lifts or supersets.
