Proper size ordering is critical for accurate size recommendations. SmartSize AI Fit Recommender requires sizes to be arranged from smallest to largest and manually confirmed before saving. This ensures the recommendation algorithm functions correctly and provides meaningful size guidance to customers.

Why Size Order Matters

Impact on Recommendations

Algorithm Dependency: Size recommendations rely on logical size progression to:

  • Determine “size up” or “size down” recommendations
  • Calculate relative fit confidence
  • Provide meaningful size alternatives
  • Handle edge cases where measurements fall between sizes

Customer Experience: Correct size ordering ensures:

  • Logical size progression in recommendations
  • Accurate “try the next size up/down” suggestions
  • Consistent sizing expectations
  • Professional appearance of size guidance

Consequences of Incorrect Ordering

Recommendation Errors:

  ❌ Wrong Order: L, S, XL, M, XS
Result: Algorithm may recommend L as smaller than S

✅ Correct Order: XS, S, M, L, XL  
Result: Logical size progression and accurate recommendations

Customer Confusion:

  • Unexpected size recommendations
  • Inconsistent sizing logic
  • Reduced confidence in size guidance
  • Increased support inquiries

Understanding Size Ranking

Rank System

SmartSize AI Fit Recommender uses a numerical rank system to track size order:

  • Rank 0: Smallest size (XS, 0, etc.)
  • Rank 1: Next smallest size (S, 2, etc.)
  • Rank 2: Medium size (M, 4, etc.)
  • Increasing ranks: Continue through largest size

Automatic Rank Assignment

When Adding Sizes:

  • New sizes get the next available rank
  • Inserted sizes push subsequent ranks up
  • Deleted sizes cause ranks to adjust downward
  • Drag and drop updates all affected ranks

Rank Consistency:

  • No gaps in rank sequence (0, 1, 2, 3…)
  • No duplicate ranks within a quiz
  • Automatic adjustment maintains sequence
  • Rank order matches visual table order

Size Reordering Methods

Drag and Drop Reordering

Basic Process:

  1. Locate Drag Handle: Find the ⋮⋮ icon on the left of each size row
  2. Click and Hold: Press and hold the drag handle
  3. Drag to Position: Move the size to its correct location
  4. Release: Drop the size in the new position
  5. Automatic Update: Ranks adjust automatically for all affected sizes

Visual Feedback:

  • Dragged row highlights during movement
  • Drop zones indicate valid placement locations
  • Other rows shift to show final positions
  • Immediate visual confirmation of new order

Keyboard Reordering

Alternative Method:

  • Use keyboard shortcuts for accessibility
  • Arrow keys to navigate between sizes
  • Specific key combinations to move sizes up/down
  • Tab navigation for screen reader compatibility

Size Ordering Requirements

Smallest to Largest Rule

Requirement: All sizes must be arranged in order from smallest to largest based on their actual size, not alphabetical order.

Correct Examples:

  ✅ Letter Sizes: XS, S, M, L, XL, XXL
✅ Numerical Sizes: 0, 2, 4, 6, 8, 10, 12
✅ Mixed System: XS, 0, S, 2, M, 4, L, 6
✅ Custom Sizes: Petite S, S, M, L, Plus L

Incorrect Examples:

  ❌ Alphabetical: L, M, S, XL, XS
❌ Random: M, XS, XL, S, L
❌ Reverse: XXL, XL, L, M, S, XS
❌ Numerical Reverse: 12, 10, 8, 6, 4, 2, 0

Measurement Consistency

Size Progression Check: Verify that measurements increase logically across sizes:

  ✅ Logical Progression:
XS: Chest 80-84cm
S:  Chest 84-88cm  
M:  Chest 88-92cm
L:  Chest 92-96cm

❌ Inconsistent Progression:
XS: Chest 90-94cm
S:  Chest 80-84cm  (smaller than XS)
M:  Chest 95-99cm
L:  Chest 88-92cm  (smaller than M)

Size Order Confirmation

Manual Confirmation Requirement

Confirmation Process: Before saving your quiz, you must:

  1. Review the size order in your table
  2. Verify sizes are arranged smallest to largest
  3. Check the confirmation checkbox: “Sizes are entered from smallest to largest”
  4. Save the quiz

Why Confirmation is Required:

  • Prevents accidental incorrect ordering
  • Ensures administrator awareness of size sequence
  • Validates intentional size arrangement
  • Required for quiz activation

Confirmation Validation

Save Validation: SmartSize AI Fit Recommender validates confirmation before saving:

  Error: "You must confirm that sizes are ordered from smallest to largest before saving"

Activation Validation: Active quizzes require confirmed size order:

  • Draft quizzes can be saved without confirmation (for testing)
  • Active status requires confirmation checkbox
  • Cannot activate quiz without size order confirmation

Best Practices for Size Ordering

Planning Your Size Order

Before Adding Sizes:

  1. List All Sizes: Write out all sizes you plan to include
  2. Arrange Logically: Put them in smallest to largest order
  3. Check Consistency: Ensure logical progression
  4. Plan Measurements: Have measurement ranges ready for each size

During Size Entry:

  1. Enter in Order: Add sizes from smallest to largest initially
  2. Verify Measurements: Check that measurements increase appropriately
  3. Test Reordering: Practice drag and drop if needed
  4. Confirm Early: Check the confirmation box as soon as order is correct

Size Naming Strategy

Consistent Naming:

  • Use standard size conventions when possible
  • Maintain consistent format throughout (all caps, all lowercase, etc.)
  • Consider customer familiarity with your chosen system
  • Document any non-standard sizing for customer reference

Clear Progression:

  • Ensure size names clearly indicate relative sizing
  • Avoid ambiguous size names that don’t suggest order
  • Consider numerical indicators for custom sizes
  • Test customer understanding of your size progression

Measurement Alignment

Ensure Measurements Match Order:

  • Verify all measurement minimums increase with size order
  • Check all measurement maximums increase with size order
  • Look for any overlaps that might confuse the algorithm
  • Test edge cases where measurements might overlap

Advanced Size Ordering

Complex Size Systems

Multi-Dimensional Sizing: Some brands use complex size systems that require careful ordering:

  Example: Women's Plus Sizes
Order: 14W → 16W → 18W → 20W → 22W → 24W
Consideration: Different cut than regular sizes
Solution: Separate quiz or clear size progression

Length Variations:

  Example: Pants with Length Options
Sizes: 32x30, 32x32, 32x34, 34x30, 34x32, 34x34
Challenge: Two-dimensional sizing
Solution: Focus on primary dimension (waist), create separate quizzes for different lengths

International Size Conversion

Global Size Standards: When serving international customers:

  • Choose primary size system for ordering
  • Provide conversion charts as reference
  • Consider regional size expectations
  • Test with customers from different markets
