      ))}
    </Masonry>
  );
}

​

Balanced vs Count Strategy

import { Masonry } from '@tuturuuu/masonry';

// Count-based (default) - Fast, no layout shift
export function CountBasedGallery() {
  return (
    <Masonry columns={3} gap={16} strategy="count">
      {items.map((item) => (
        <div key={item.id} style={{ height: item.height }}>
          {item.content}
        </div>
      ))}
    </Masonry>
  );
}

// Height-based - Better visual balance for varying heights
export function BalancedGallery() {
  return (
    <Masonry columns={3} gap={16} strategy="balanced">
      {items.map((item) => (
        <div key={item.id} style={{ height: item.height }}>
          {item.content}
        </div>
      ))}
    </Masonry>
  );
}

​

With Smooth Transitions (v0.3.0+)

import { Masonry } from '@tuturuuu/masonry';

export function SmoothTransitionsExample() {
  const items = Array.from({ length: 16 }, (_, i) => ({
    id: i,
    height: [120, 180, 150, 200][i % 4],
  }));

  return (
    <Masonry
      columns={4}
      gap={16}
      strategy="balanced"
      smoothTransitions={true}
      balanceThreshold={0.05}
    >
      {items.map((item) => (
        <div
          key={item.id}
          style={{ height: `${item.height}px` }}
          className="flex items-center justify-center rounded-lg bg-blue-500 text-white"
        >
          Item {item.id + 1}
        </div>
      ))}
    </Masonry>
  );
}

​

Custom Balance Threshold (v0.3.0+)

import { Masonry } from '@tuturuuu/masonry';

export function CustomThresholdExample() {
  return (
    <Masonry
      columns={3}
      gap={20}
      strategy="balanced"
      balanceThreshold={0.1} // Higher = more tolerance for imbalance
    >
      {items.map((item) => (
        <div key={item.id}>{item.content}</div>
      ))}
    </Masonry>
  );
}

​

How It Works

​

Count Strategy Algorithm

1. Creates the specified number of columns
2. Iterates through all items
3. Places each item in the column with the fewest items
4. Uses strict comparison for deterministic distribution
5. Memoized - only recalculates when children or columns change

​

Balanced Strategy Algorithm (v0.3.0+)

1. Immediate Multi-Column Render: Items appear instantly in their target columns
2. ResizeObserver Setup: Observes all masonry items for size changes
3. Event-Driven Measurement: Captures height changes as they happen (images loading, etc.)
4. Intelligent Distribution:
   • Calculates running average for unmeasured items
   • Uses threshold-based greedy algorithm
   • Considers balance threshold for tie-breaking
   • Tracks coefficient of variation for quality
5. Ultra-Aggressive Optimization (v0.3.10 enhanced):
   • Phase 1: Min-Max placement (evaluates all placements)
   • Phase 2: Exhaustive search (tries moving EVERY item to EVERY column)
   • Phase 3: Best-move selection (applies single best improvement)
   • Phase 4: Build layout from optimized assignments
   • Up to 50 passes exploring all N×M possibilities (vs previous 20)
   • Stops only when columns within 0.5% or 5px of each other (vs previous 1% or 10px)
   • Near-perfect balance with ≤5px difference between columns
6. Smart Redistribution (v0.3.2 enhanced):
   • Debounced 500ms after last change for maximum stability
   • Only triggers when heights change >10px (ignores all minor fluctuations)
   • Maximum 10 redistributions to prevent endless movement
   • Stops observing after all images load
   • Stops observing after 2 seconds of stability
   • Uses requestAnimationFrame for smooth visual updates
   • Memoized to prevent unnecessary calculations
7. Automatic Cleanup: Observer disconnects on unmount or strategy change

​

Responsive Behavior

• Without breakpoints: Uses fixed columns value
• With breakpoints: Adjusts columns based on viewport width

​

Performance Considerations

​

v0.3.0 Performance Improvements

​

Strategy Performance

• Count Strategy (Default): Fastest option. No height measurements, no layout shift, zero overhead. Ideal for most use cases and 100+ items.
• Balanced Strategy (v0.3.10): Modern ResizeObserver API with ultra-aggressive exhaustive optimization and rock-solid stability controls. Event-driven with exhaustive search (tries all item×column moves in up to 50 passes) for near-perfect visual balance, 500ms debounce, 10px threshold, max 10 redistributions, and auto-stop after images load. Professional layouts with column heights differing by ≤5px and ultra-tight 0.5% tolerance.

​

Memoization Benefits

• Distribution calculation: Only runs when dependencies change
• Average height calculation: Cached between renders
• Column wrappers: Prevents unnecessary array allocations
• Result: Smooth 60fps even with 100+ items

​

When to Use Each Strategy

​

Styling

<Masonry
  columns={3}
  gap={16}
  className="mx-auto max-w-7xl px-4"
>
  {items.map((item) => (
    <div
      key={item.id}
      className="rounded-lg bg-gradient-to-br from-blue-500 to-purple-600 p-4"
    >
      {item.content}
    </div>
  ))}
</Masonry>

​

Best Practices

​

How Balanced Strategy Works (v0.3.0+)

1. Immediate Multi-Column Render: Items appear instantly in their target columns (no single-column phase)
2. ResizeObserver Setup: Creates observer to monitor all masonry items for size changes
3. Event-Driven Measurement: Captures height changes automatically when they occur (images loading, dynamic content)
4. Accurate Measurement: Uses entry.contentRect.height from ResizeObserver for precision
5. Validation & Fallbacks: Validates measurements; uses running average for missing/invalid values
6. Smart Change Detection (v0.3.2): Only redistributes when heights change by >10px (completely ignores minor fluctuations)
7. Item Migration (v0.3.8 new):
   • Phase 1: Min-Max placement minimizes height range
   • Phase 2: Up to 10 iterative balancing passes
   • Each pass moves best item from tallest to shortest column
   • Stops when range < max(20px, 5% of shortest)
   • Direct migration achieves excellent column equality
8. Aggressive Debouncing (v0.3.2): 500ms debounce + requestAnimationFrame ensures maximum stability
9. Redistribution Limits (v0.3.2): Maximum 10 redistributions prevents endless movement
10. Image Load Tracking (v0.3.2): Automatically stops observing once all images finish loading
11. Stability Detection (v0.3.2): Stops observing after 2 seconds of no changes
12. Memoized Calculations: Distribution only recalculates when dependencies actually change
13. Auto-Cleanup: Observer automatically disconnects on unmount or strategy change

• ✅ 50-70% faster - event-driven vs polling (100ms intervals in v0.2.x)
• ✅ Instant response - no 100ms delay for updates
• ✅ Better battery life - no continuous polling
• ✅ Minimal memory - single observer instance vs growing listeners
• ✅ Memoized calculations - prevents unnecessary work
• ✅ Smooth 60fps - even with 100+ items
• ✅ Robust validation - handles edge cases gracefully
• ✅ No layout shift - multi-column from first render
• ✅ Item Migration (v0.3.8) - Direct balancing moves items from tall to short columns
• ✅ Iterative optimization (v0.3.8) - Up to 10 passes with smart stopping for excellent balance
• ✅ Aggressive debouncing (v0.3.2) - 500ms wait ensures rock-solid stability
• ✅ High thresholds (v0.3.2) - 10px minimum change completely ignores minor adjustments
• ✅ Auto-stop (v0.3.2) - Stops observing after images load or 2s of stability
• ✅ Redistribution limit (v0.3.2) - Maximum 10 redistributions prevents endless movement

​

Browser Support for ResizeObserver

• Supported: All modern browsers (Chrome 64+, Firefox 69+, Safari 13.1+)
• Fallback: Logs warning and gracefully degrades to count strategy if unavailable

​

Additional Performance Notes

  • 500ms debounce ensures maximum stability
  • Maximum 10 redistributions prevents endless movement
  • Auto-stops after all images load
  • Auto-stops after 2 seconds of stability
  • Memoized distribution prevents recalculation unless dependencies change
  • Proper ResizeObserver cleanup on unmount
• Minimal re-renders when breakpoints change

Migration Guide

​

Migrating from v0.2.x to v0.3.0

// ❌ v0.2.x - Might show fewer columns than expected
<Masonry columns={4} />
// Default breakpoints override columns based on screen width

// ✅ v0.3.0 - Works as expected
<Masonry columns={4} />
// Always shows 4 columns

// If you want responsive behavior, explicitly provide breakpoints:
<Masonry 
  columns={4}
  breakpoints={{ 640: 1, 768: 2, 1024: 3, 1280: 4 }}
/>

1. Test your layouts: If you were relying on default breakpoints, explicitly add them
2. Update imports: No changes needed
3. Check columns prop: Should now work as expected without breakpoints
4. Optional: Consider using new balanceThreshold and smoothTransitions props

• You were already passing explicit breakpoints prop
• You were passing empty breakpoints breakpoints={{}}
• Your layouts already work correctly

• balanceThreshold - Fine-tune distribution sensitivity
• smoothTransitions - Add CSS animations during redistribution
• Better performance with ResizeObserver (automatic)
