Example Test Cases

✅ Exact Match Test

Target: 120kg, Bar: 20kg, Basic inventory → Result: 2×20kg + 2×10kg per side (exact match)

⚠️ Impossible Weight Test

Target: 121kg with basic inventory → Shows closest alternatives with delta

❌ Invalid Input Test

Target ≤ bar weight (e.g., 20kg) → Error: target must exceed bar weight

How to Use This Plate Calculator

Enter your target weight and select your bar type. The calculator will show you exactly which plates to load on each side of the barbell using the most efficient combination.

Why Use a Plate Calculator?

A plate calculator saves time and prevents errors when loading the bar. Benefits include:

  • Save time - No mental math between sets
  • Avoid errors - Loading the wrong weight is dangerous
  • Efficient loading - Uses the fewest plates possible
  • Learn patterns - Memorize common combinations faster

Common Weight Combinations

Memorize these standards for quick loading with a 45 lb bar:

  • 135 lbs - 1 × 45 lb plate per side
  • 225 lbs - 2 × 45 lb plates per side
  • 315 lbs - 3 × 45 lb plates per side
  • 405 lbs - 4 × 45 lb plates per side

Different Bar Types

Always account for the bar weight:

  • Standard Olympic Bar - 45 lbs (20 kg)
  • Women's Bar - 35 lbs (15 kg)
  • Safety Squat Bar - 60-70 lbs
  • Trap/Hex Bar - 45-60 lbs

Pro Loading Tips

  • Load heavy first - Start with 45s, then add smaller plates
  • Use collars - Always secure plates with collars
  • Unload symmetrically - Remove from both sides alternately
  • Match heights - Keep bar level with same plate types
