Fabric consumption and costing of a basic T-Shirt

Sl.	Measurement	Size(M)			cm
1.	Full Body Length	65 cm	Full Body length = Front length+ Allowance+ Hem height	=65+1+2	=68
2.	½ Chest Width	54 cm	(Front Full) ½ Chest Width = ½ Chest+ Allowances	=54+1+1	=56
3.	Full Sleeve Length	24 cm	Full sleeve length =  Sleeve length+ Allowance+ Hem	=24+1+2	=27

Fabric consumption per piece

= [{(Full Body Length + Full Sleeve Length)× ½ Chest Width×  Garments Parts × GSM} / 100×100×1000] +    Wastage % ( of use)

 

= [{(68+27) × 56× 2× 200}/100×100×1000] + 10% of Consumption

 

= [{95× 56× 2× 200}/10000000] +10% of Consumption

 

= 0.2128 + 10% of 0.212

 

= 0.2128+ 0.02

= 0.2328 or 0.23 kg/piece
