• Measure each wall and note the measurements on your plan. It is recommended to note the 
placement and size of any doors, windows, or openings in the room.
• Also identify the angle of each corner. (Figure 1.1)
• Add all of the wall lengths together to get the total amount of moulding you need to purchase. 
Add 15% for cutting mistakes and waste.

Safety Tips
• If possible, have someone assist you in holding your moulding while using the cutting cart. 
• If you remove a safety cable, please replace them. This will help moulding from falling out of 
the rack and possibly striking you or another customer. 
• Be careful when lifting heavy mouldings or propacks, if it is too heavy for you to lift on your 
own, ask a Home Depot associate for help.
