Anthropometric Hip Breadth Percentile Seat Width Fit Checker

Audit actual hip/seat samples with separately measured clothing breadth and total caller side-clearance allowance; does not invent demographic percentiles or infer armrest clearance.

Description

Hip-to-seat fit includes clothing breadth and a total side-clearance allowance.

Hip-to-seat fit includes clothing breadth and a total side-clearance allowance. It is distinct from elbow clearance at armrests.^[1]

Enter aligned nonempty nonnegative centimeter widths/hip/clothing lists and nonnegative total side allowance. Return clothed breadths, signed margins and inclusive binary fit flags.

When to use Anthropometric Hip Breadth Percentile Seat Width Fit Checker

Use Anthropometric Hip Breadth Percentile Seat Width Fit Checker when you need to evaluate the supplied records under the calculation and evidence rules below. No demographic percentile, body-size estimate or armrest inference is supplied.

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.

How to use Anthropometric Hip Breadth Percentile Seat Width Fit Checker and understand its results

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
Enter seatClearWidthsCm, measuredHipBreadthsCm, clothingAddedBreadthsCm, callerRequiredTotalSideClearanceCm using the field table and calculation rules, then run the tool.
Read clothedHipBreadthsCm, signedSeatWidthMarginsCm, withinCallerHipSeatFitFlags. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
seatClearWidthsCm	Seat clear widths cm	list of number	Required
measuredHipBreadthsCm	Measured hip breadths cm	list of number	Required
clothingAddedBreadthsCm	Clothing added breadths cm	list of number	Required
callerRequiredTotalSideClearanceCm	Caller required total side clearance cm	number	Required

Enter aligned nonempty nonnegative centimeter widths/hip/clothing lists and nonnegative total side allowance. Return clothed breadths, signed margins and inclusive binary fit flags.

clothedHip=hip+clothing; margin=seatWidth−clothedHip−totalAllowance

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
clothedHipBreadthsCm	Clothed hip breadths cm	list of number
signedSeatWidthMarginsCm	Signed seat width margins cm	list of number
withinCallerHipSeatFitFlags	Within caller hip seat fit flags	list of number

Limitations and assumptions

No demographic percentile, body-size estimate or armrest inference is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Armrest Elbow Clearance Width Checker: Inside-armrest clearance needs room for clothed elbow breadth and two side allowances. Total width is not a seat-width percentage. For a complementary task, use Seat Depth Buttock-Popliteal Fit Checker: Seat-depth fit is an observed behind-knee gap check. Sample coverage describes measured people rather than a population percentile.
