Olympic vs standard barbells
The real difference is the sleeve: Olympic bars take plates with a 2-inch (50 mm) hole, standard bars take plates with a 1-inch hole. Weight, length and strength follow from that.

| Olympic bar | Standard bar | |
|---|---|---|
| Sleeve / plate hole | 2 in (50 mm) | 1 in (about 25–28 mm) |

| Sleeves | Rotate on bushings or bearings | Usually fixed |
| Typical load rating | Several hundred kg / 600+ lb | Often 200–300 lb |
| Where you'll see it | Commercial gyms, competitions | Older home sets, light dumbbell-style bars |
Plates only fit one kind of bar
Olympic plates slide straight off a standard bar's thin sleeve, and standard plates won't fit over an Olympic sleeve. Adapter sleeves exist to put Olympic plates on a standard bar, but they're a workaround, not a fix.
Which should you buy?
For a home gym where you'll squat, bench and deadlift, buy an Olympic bar and Olympic plates. They hold far more weight, the rotating sleeves are easier on wrists and elbows in fast lifts, and every gym, coach and program assumes them. Standard bars only make sense for very light, low-budget setups or for curl-style training.
Doing the math on either bar
Set your bar's real weight in the plate calculator (pick Custom under Bar for a standard bar) and every load includes it. Not sure what yours weighs? See how much a barbell weighs.

Questions
Do Olympic plates fit a standard bar?
No. Olympic plates have a 2-inch hole and slide around on a 1-inch standard sleeve. You'd need adapter sleeves, which aren't ideal for heavy lifting.
How much does a standard barbell weigh?
Usually 15–25 lb (7–11 kg), depending on length. Check the label or weigh it.
Why do Olympic bar sleeves spin?
Rotating sleeves let the plates stay put while the bar turns in your hands, which matters in cleans and snatches and makes heavy lifts easier on the joints.
