According to IS (Indian Standard) method of measurement, what is the conventional order for booking dimensions?

Introduction / Context:
A uniform dimension-order convention avoids confusion during take-off and billing. Indian Standard measurement practice prescribes a consistent sequence across items so that multiplication and checking are straightforward.

Given Data / Assumptions:

• The question refers to the IS method of measurement (e.g., IS 1200 series).
• We seek the conventional dimension order.

Concept / Approach:
Dimensions are typically recorded as Length first (along the primary run), Breadth (thickness or secondary span) second, and Height (or depth/vertical) last—commonly abbreviated LBH. This standardization helps maintain clarity in quantity abstracts and reconciliations.

Step-by-Step Solution:
Identify the dominant horizontal dimension as Length.Record the secondary horizontal dimension as Breadth.Record the vertical dimension as Height.Thus, the order is Length, Breadth, Height.

Verification / Alternative check:
Cross-check with standard schedules and textbooks—LBH is the commonly cited sequence.

Why Other Options Are Wrong:

• Other permutations depart from the convention and invite mistakes in multiplication.

Common Pitfalls:
Switching dimension order between items; misinterpreting breadth vs. thickness.

Final Answer:
Length, breadth, height
