Hi, I dun think the calculation is so simple. you need to cater for wastage as when they paste two pieces together, they have to get the pattern of the adjacent wall paper align. Intially, i have 1 normal range wall paper for my master bedroom headboard( 4.7m length, $450) another premium wall paper for my TV console( 5ft included in my TV console quotation). however, the premium one seem to be different when delivered. Edge of the premium wall paper is yellow and missing of one colour. The pink shade become very light peach. I get my wall paper though my contractor. At least, my contractor change the wall paper FOC for another piece. And i choose a new piece from another company as I was quite frustrated with the yellowish looking premium wall paper as I waited 2 weeks for the shipment. The premium wall paper delayed my house renovation. Normally, premium wall paper is imported from Europe and will take longer for shipment. After my renovation, I think gng through contractor will be easily. At least they help me to settle with some of the defect. And if you in hurry dun get wall paper from Europe.
