Thread Consumption || Sewing thread consumption of a garments

Machine Thread per inch stitching for sewing
Plain Machine - Single needles 2.75 inches
Plain Machine - Two needles 5.5 inches
Over lock Machine - Three threads 15 inches
Over lock Machine - Four threads 18.75 inches or 20 inches
Over lock Machine - Five threads 23 inches
Safety stitch 20 inches
Flat lock stitch 22 inches
Chain stitches - one needles 12.5 inches
Chain stitches - two needles 25 inches
Button Hole 24 inches
Bar take machine 26 inches


Suppose, we will estimate sewing thread consumption for kid’s basic T-shirt and T-shirt has used 94 inch four thread over lock stitching, flat lock 48 inches, two needle chain stitches 18 inches and plain machine one needle 30 inches.

Now, as per above information the sewing thread consumption of kid’s basic T-shirt is;
In meter: (94 x 4 thread O/L) + (48 x F/L) + (18 x 2 needles chain stitches) + (30 x one needle P/M)
= (94 x 18.75) + (48 x 22) + (18 x 25) + (30 x 2.75)
= 1762.5 + 1056 + 450 + 82.5
= 3351 inch
= 3351 inch / 39.37 = 85 meter (As we know, 1 meter = 39.37 inches)
= 85 meter + 15% wastage
= 98 meter / body
So, as per above information, we need sewing thread for basic kid’s T-shirt is 98 meters per garment to complete the cloth stitching.

Suppose, our bulk order quantity is 150,000 pcs for basic T-shirt style and our sewing thread consumption is 98 meters per body. If per cone sewing thread is 4000 meters, then what will be the bulk sewing thread consumption for 150,000 pcs garments?

Total order quantity x Sewing thread per body / Per cone sewing thread
= 150,000 x 98 / 4000
= 3675 cones
So, we need 3675 cones for completing sewing 150,000 pcs garments
