Plate Calculator

Instantly calculate which plates to load on your barbell. Never count plates in your head again.

How many plates do I need for a certain weight?

For 100kg with Olympic barbell (20kg): load 2×20kg plates per side. For 225lb: 2×45lb per side. Enter any weight in the calculator below to see exactly which plates to load.

Standard Olympic Plates

Metric (kg): 25, 20, 15, 10, 5, 2.5, 1.25

Imperial (lb): 45, 35, 25, 10, 5, 2.5

Note: Standard Olympic barbells weigh 20kg (45lb) for men and 15kg (35lb) for women. The calculator shows plates needed per side of the barbell.

Standard Olympic Plates

Olympic weightlifting and powerlifting use standardized plate weights. Understanding these helps you quickly calculate loads:

Metric System (kg)

25kgLargest standard plate, used for heavy lifts
20kgMost common plate for working sets
15kgOften used for warm-ups and accessories
10kgGood for incremental loading
5kgStandard increment plate
2.5kgFine-tuning for progressive overload
1.25kgMicro-loading for slow progression

Imperial System (lb)

45lbStandard plate, equals about 20.4kg
35lbLess common, about 15.9kg
25lbCommon increment, about 11.3kg
10lbStandard small plate
5lbSmall increment plate
2.5lbMicro plate for fine adjustments

Barbell Types and Weights

Different barbells have different weights. Make sure you're using the correct bar weight in your calculations:

TypGewichtDauerNutzen
Men's Olympic Bar20kg / 45lb2.2m / 7.2ftStandard for all compound lifts
Women's Olympic Bar15kg / 35lb2.01m / 6.6ftSmaller diameter grip, shorter length
Trap/Hex Bar20-32kg / 45-70lbVariesDeadlifts, shrugs - weight varies by model
EZ Curl Bar7-11kg / 15-25lb1.2m / 4ftBicep curls, tricep work
Safety Squat Bar25-32kg / 55-70lb2.2m / 7ftEasier on shoulders for squats

Common Barbell Loads

Here are some frequently used barbell loads and their plate configurations:

Metric (kg)

60kg20kg bar + 20kg per side

100kg20kg bar + 20kg + 20kg per side

315lb45lb bar + 45lb + 45lb + 45lb per side
405lb45lb bar + 45lb × 4 per side

Loading Tips

  • Always load plates evenly on both sides to prevent tipping
  • Use collars/clips to secure plates, especially for dynamic movements
  • Load largest plates first (closest to sleeves), smallest last
  • Double-check your math before attempting heavy lifts
  • Consider using fractional plates (0.5-1.25kg) for steady progression

Progressive Loading Strategy

How you add weight over time is critical for long-term progress. Here are proven strategies:

Linear Progression

Add 2.5kg (upper body) or 5kg (lower body) each session when you complete all prescribed reps

Beginners (first 6-12 months)

Double Progression

First increase reps within a range (e.g., 8→12), then add weight and drop back to lower reps

Intermediates

Microloading

Use 0.5-1.25kg fractional plates for slower, steady gains when regular jumps stall

Advanced lifters, small muscle groups

💡 When progress stalls with regular plates, microplates can extend your progression by months.

Safety Checklist for Loading

Proper loading technique prevents accidents. Run through this checklist before every heavy lift:

Collars secured

Prevents plates sliding off during the lift — critical for dynamic movements

Even loading both sides

Uneven load causes bar tilt and puts asymmetric stress on your body

Plates fully seated

Loose plates can shift mid-lift, changing the weight distribution

Weight verified before lift

Mental math errors are common — misloading can cause failed lifts or injury

Spotter or safeties in place

Always have a bailout option for heavy compound lifts

Common Loading Errors to Avoid

These mistakes are more common than you'd think — even experienced lifters make them:

Forgetting the bar weight

Always count: bar weight + plates on both sides combined. The bar is part of the total.

Mental math mistakes

Use this calculator or double-check with a training partner before heavy attempts.

Using the wrong bar

Verify bar weight before loading — commercial gyms often have bars of different weights.

Mixing kg and lb plates

Some gyms have both metric and imperial plates. Check the numbers before loading.

Loading asymmetrically

Always add plates to both sides alternately to prevent the bar from tipping.

Equipment Variations by Gym Type

Different gyms have different equipment. Know what to expect:

StudioartScheibenHantelstangen
Commercial GymOften lb plates, may have limited microplate selectionStandard 45lb bars, may have women's bars available
Powerlifting GymCalibrated kg plates (accurate to ±10g), full microplate selectionSpecialized power bars, deadlift bars, squat bars
CrossFit BoxBumper plates (kg), often color-coded per IWF standardsOlympic bars, technique bars, various specialty bars
Home GymVaries widely — know your own equipment weights preciselyMay have non-standard bars — weigh them once accurately

💡 When visiting a new gym, spend a few minutes familiarizing yourself with their equipment before training.

Common Barbell Loading Myths Debunked

All barbells weigh 20kg/45lb

Bars vary: women's Olympic bar is 15kg, EZ bars are 7-11kg, trap bars are 20-32kg. Always check your specific bar's weight.

Colored plates are just aesthetic

Competition plate colors follow IWF standards for rapid identification: red (25kg), blue (20kg), yellow (15kg), green (10kg).

You don't need to count plates carefully

Loading errors are common and can cause imbalances or injuries. Always double-check before heavy lifts.

Microplates are useless

0.5-1.25kg fractional plates allow gradual progression that's crucial for intermediate/advanced lifters who can't add 2.5kg weekly.

The barbell doesn't count in the total

The barbell is ALWAYS included in the total weight lifted. A 100kg squat means bar + plates = 100kg total.

Frequently Asked Questions

Wie benutze ich den Hantelscheibenrechner?

Gib dein Zielgewicht ein, wähle deinen Hanteltyp (Standard 20kg/45lb oder Damen 15kg/35lb) und der Rechner zeigt dir genau, welche Scheiben du auf jede Seite der Hantel laden musst.

Welche Scheiben verwendet dieser Rechner?

Der Rechner verwendet olympische Standardscheiben. Metrisch: 25, 20, 15, 10, 5, 2,5 und 1,25 kg. Imperial: 45, 35, 25, 10, 5 und 2,5 lb.

Warum kann ich bestimmte Gewichte nicht erreichen?

Manche Gewichte sind mit Standardscheiben nicht erreichbar. Zum Beispiel erfordert 101 kg eine 0,5-kg-Scheibe, die nicht zum Standard gehört. Der Rechner sagt dir, ob dein Zielgewicht mit den verfügbaren Scheiben nicht erreicht werden kann.

Wie viel wiegt eine olympische Hantelstange?

Eine olympische Herren-Standardhantelstange wiegt 20 kg (45 lb). Eine olympische Damenhantelstange wiegt 15 kg (35 lb). Einige Spezialhanteln (Safety Squat Bar, Trap Bar) können andere Gewichte haben.

Sind die Scheibenfarben korrekt?

Die Farben folgen dem IWF-Standard (Internationaler Gewichtheberverband) für Wettkampfscheiben: Rot für 25 kg, Blau für 20 kg, Gelb für 15 kg, Grün für 10 kg. Scheiben im Fitnessstudio können jedoch abweichen.

Wie rechne ich zwischen kg und lb um?

Um kg in lb umzurechnen, multipliziere mit 2,205 (z. B. 100 kg × 2,205 = 220,5 lb). Um lb in kg umzurechnen, multipliziere mit 0,453 (z. B. 225 lb × 0,453 = 102 kg). Gängige Entsprechungen: 20 kg ≈ 45 lb, 60 kg ≈ 135 lb, 100 kg ≈ 225 lb.

Was ist der Unterschied zwischen Bumper Plates und Gusseisenplatten?

Bumper Plates bestehen aus Gummi mit Stahlkern und können sicher fallen gelassen werden – unverzichtbar für olympische Hebungen. Gusseisenplatten sind aus Metall, kompakter, können aber den Boden beschädigen, wenn sie fallen gelassen werden. Bumper Plates folgen der IWF-Farbkodierung, Gusseisenplatten variieren je nach Hersteller.

Muss ich das Gewicht der Verschlüsse mitzählen?

Standard-Federverschlüsse wiegen insgesamt etwa 0,5 kg (1 lb) pro Paar – normalerweise vernachlässigbar. Wettkampfverschlüsse wiegen 2,5 kg pro Stück (5 kg insgesamt). Wenn du schwere Verschlüsse im Wettkampf verwendest, berücksichtige sie in der Gesamtgewichtsberechnung.
