Wallpaper Calculator wahi tarike se count karta hai jaise ek decorator karta hai, area formula se nahin. Wallpaper vertical strips mein lagta hai: har strip wall height plus margin par cut hoti hai, aur pattern ki poori repeat tak round-up hoti hai taaki design agli strip se match kare. Ek roll se pure strips hi milti hain — 10 metre ka roll 2.77 metre ki teen strips deta hai, aur bacha hua metre bekaar cutting hai. Isliye area-based estimates patterned wallpaper par kam pad jaate hain: 53 cm ki repeat har strip par aadha metre tak waste kar sakti hai, aur sirf strip-counting hi ye dekhti hai.

Common errors aur troubleshooting
Square metre calculation se zyada rolls maang raha hai. — Area formulas strip cutting ignore karte hain. Ek roll se sirf pure strips milti hain aur repeat har strip ko upar round karti hai — dono losses real hain.
Doors-windows subtract nahin kiye. — Standard practice normal openings ignore karna hai: unke aas-paas ke cuttings shayad hi kahin aur kaam aayein, aur margin errors cover kar deta hai. Sirf bahut bade openings subtract karein.
Same wallpaper ke do lots wall par alag dikhte hain. — Print batches ke beech dye halka change hota hai. Saare rolls same batch number ke kharidein aur ek spare rakhein.
Aksar pooche jaane wale sawaal
Har wall ke liye kitne rolls chahiye?
Wall length ko roll width se divide karein strips ke liye; phir dekhein aapki height aur repeat-rounding par ek roll kitni pure strips deta hai, aur divide karein. 2.5 m height wali 4 m wall 53 cm rolls mein 8 strips maangti hai: plain wallpaper ke 3 rolls.
Label par pattern repeat ka matlab kya hai?
Vertical distance jiske baad design repeat hota hai. Har strip ko us value ke multiple mein cut karna zaruri hai taaki strips ke beech design match kare; farak waste ban jaata hai.
Kya windows-doors subtract karne chahiye?
Aam taur par nahin. Openings ke aas-paas cut hue pieces kahin aur kaam nahin aate, aur unhe count mein rakhna wahi safety margin deta hai jo har decorator chahta hai.
Kitna extra kharidein?
Ek spare roll standard buffer hai: ye ek galat cut, installation ke dauraan damaged strip, aur usi batch se future repair cover karta hai.
