One Arm at a Time
Dumbbell Curl Strength Standards
Every number on this page is one dumbbell, not the pair, because that is how you pick them off the rack. Enter your bodyweight to see the beginner to elite dumbbell curl figures for your size, and find out which level the weight you actually use puts you in.

What the Dumbbell Curl Really Measures
The same elbow flexors, with the wrist set free.
A dumbbell curl trains the same elbow flexors as a barbell curl, but each arm works on its own and the wrist is free to rotate. Most lifters start with the palm neutral and turn it up as the weight rises, which brings the biceps into a stronger line of pull near the top. Working one arm at a time also means the stronger side cannot quietly carry the weaker one, which is the main reason coaches keep dumbbell curls in a programme that already has barbell curls.
The independence comes at a price in load. Two dumbbells almost never add up to a barbell curl of the same total, because stabilising two separate weights costs something and because the supinated path is longer. Expect the pair together to fall a little short of the barbell figure, and expect one hand to be worth roughly half of it.
Where These Numbers Come From
Half of the strict barbell curl standard, per hand.
These figures are derived in two steps. First the strict barbell curl standard is taken from the bench press standard on our strength standards page, at 50 percent of the bench at beginner level falling to 33 percent at elite. Then each single dumbbell is set at half of that barbell figure, which is the ratio most lifters land on when they test both honestly.
That two-step derivation is deliberate. It means the dumbbell curl page and the barbell curl page can never drift apart, and it means a lifter who improves on one should see the other move with it. If your dumbbell curl is far ahead of half your barbell curl, the likely explanation is that your barbell curl is stricter than your dumbbell curl, not that your arms behave unusually.
| Level | Share of the bench press standard |
|---|---|
| Beginner | 25 percent |
| Novice | 23 percent |
| Intermediate | 21 percent |
| Advanced | 18.5 percent |
| Elite | 16.5 percent |
These standards are estimates derived from typical ratios to the main lifts, rounded to the nearest 5 lb. The bench, squat, deadlift and overhead press figures they are built on are the bodyweight-ratio approximations published on our strength standards page, which are aligned with widely used references in the strength and conditioning field including ExRx.net. Nothing here is measured lab data, and no table anywhere else has been copied. Treat every figure as a target to aim at, not a verdict on you.

A Worked Example
Reading a rack of dumbbells against the table.
A 190 lb man has an intermediate dumbbell curl of 40 lb per hand and an advanced mark of 55 lb. If he curls the 30s for ten strict reps, that estimates to about 40 lb for a single, which puts him right on the intermediate mark.
Because dumbbells usually go up in 5 lb steps, that lifter has only three or four rungs of the rack between intermediate and advanced. It is worth being patient with that ladder: adding reps at 35 lb before reaching for the 40s is how the jump actually happens, and a curl grabbed with a shrug and a lean does not count for this table.
What These Standards Cannot Tell You
Coarse steps, loose form and a very small muscle.
Dumbbells come in 5 lb jumps in most gyms, which is a large relative increase on a lift this small. Going from 30 to 35 is a 17 percent jump, so a single number cannot describe your strength very precisely, and moving up a level often takes a couple of months of rep progress rather than a sudden change.
Form drifts easily here too. Standing curls invite a hip swing, seated ones invite a shoulder roll, and both quietly raise the weight you can move. These standards assume a controlled curl with the upper arm still, so if you want an honest read, do the test seated with your back supported.

Frequently Asked Questions
Common questions about these standards.
How much should I be able to dumbbell curl?
At 190 lb bodyweight the intermediate dumbbell curl is about 40 lb per hand and the advanced mark is about 55 lb. At 140 lb an intermediate woman is near 20 lb per hand. Enter your bodyweight above for your own figures.
What is the average dumbbell curl weight?
For a 190 lb man who trains, an honest single sits between the novice and intermediate rows, about 35 to 40 lb per hand, so most working sets happen with 25 to 35 lb dumbbells. For a 140 lb woman the same band is about 15 to 20 lb per hand.
Are these numbers per dumbbell or for both?
Per dumbbell. The figure is the weight of the single dumbbell you pick off the rack, which is how everybody talks about curls in practice.
Is curling 50 lb dumbbells good?
For a man around 190 lb that is at the advanced end of this scale, assuming the reps are controlled and the upper arm stays still. With a swing behind it the same weight means considerably less.
Why is my dumbbell curl less than half my barbell curl?
Usually because the barbell version is being done with more help from the body, or because you curl the dumbbells with a strict pause and the barbell with momentum. Test both the same way and the halves usually line up.
How are these dumbbell curl standards calculated?
Each level is half of the strict barbell curl standard, which is itself a share of the bench press standard for the same bodyweight and sex, all rounded to the nearest 5 lb. They are estimates derived from typical ratios between lifts.
