Formula for Calculating Sewing Room Capacity (2024)

The formula used for calculating the available capacity of the sewing line is discussed here. The available capacity of a line is presented in minutes or hours.

Sewing room Capacity per Day= {(No. of machine x daily work hours x 60) – absenteeism %} x Efficiency % (unit in minutes)

Formula for Calculating Sewing Room Capacity (1)
Sewing Line

Monthly Capacity = Daily Capacity X No. of working days in a month

The capacity of a line depends on the average efficiency% of the line and operator absenteeism%. First, line-wise capacity is calculated and then added all line's capacity to calculate the available capacity of the floor.

Things you need to know prior to using the above formula for calculating line capacity

  • Number of sewing machine in a line
  • Shift hours in a day
  • Average operatorabsenteeismpercent
  • Average line efficiency%

An example:

A factory floor has 5 lines. The factory works for 8 hours daily. No of total operators, line efficiency, and absenteeism percentage are as given in the following table.

Available capacity of the line will vary on the factors such as
i) no. of operators working in the line,
ii) Line’s existing efficiency and
iii) operator absenteeism percentage.

Capacity can be also represented in pieces. To get it, divide total capacity (in minutes) by SAM of the garment to be made on the floor. Suppose a factory produces basic full sleeve shirt of SAM 20. The shirt production capacity of the floor will be 1463 pieces per day (29268/20).

Let's use our formula V = l x w x h. After multiplying the length, width, and height, we know that Katie's box measures 96 cubic inches. Example 2: Mark is at the beach and wants to fill his bucket with water to build a castle. The bucket can hold 2 gallons of water.

What is the formula for calculating production capacity? ›

A basic way to find out the production capacity is by multiplying the number of available workstation capacity by the available time in a work shift. For example, if a machine's design capacity is 10 units in an hour and the work shift is 8 hours, the production capacity for the machine is 80 units per shift.

How to calculate space capacity? ›

The formula is as followed:
  1. Usable Space = Total Sq. Ft. – Non-Storage Space Sq. Ft.
  2. 150,000 Sq. Ft. – 30,000 Sq. Ft. = 120,000 Sq. Ft.
  3. Storage Capacity = Usable Space in Sq. Ft. * Maximum Stack Height in Ft.
  4. 120,000 Sq. Ft. * 30 Ft. = 3,600,000 Cubic Feet.
