Fence Calculator un counting details ko sahi karta hai jo ek jaldi wala sketch galat kar deta hai. Ek open run mein posts sections se ek zyada hote hain — classic fencepost rule — isliye 2.4 metre spacing par 30 metre 13 sections aur 14 posts hai, 12 aur 12 nahin. Rails sirf panel sections se multiply hote hain, kyunki ek gate ek section leta hai par rails-pickets nahin: gate hardware ki tarah aata hai. Pickets bina-gate wale hisse ko “picket width plus gap” ki pitch se bharti hain, aur har post hole ke liye concrete chahiye — yahan per post 0.5 cubic feet maankar, 50-lb bags mein convert kiya gaya hai, wahi unit jo shop bechti hai.

Common errors aur troubleshooting
Posts ki ginti expected se ek zyada hai. — Yahi fencepost rule hai. N sections ki run mein N+1 posts lagte hain kyunki dono ends par ek-ek chahiye — mathematics ki sabse purani “off by one” error, yahan jaan-bujhkar avoid ki gayi.
Ek closed loop mein ek post extra dikhta hai. — Closed ring mein posts utne hi hote hain jitne sections, kyunki last post hi first hai. Jab fence starting point par wapas aaye tab ek post subtract karein.
Kharide gaye pickets kaam khatam hone se pehle khatam ho gaye. — Cuts, cracks aur culls ke liye 5–10% add karein. Calculator geometric count deta hai; buffer aapka hai.
Aksar pooche jaane wale sawaal
30 metre fence ke liye kitne posts chahiye?
2.4 m spacing par ye 13 sections hai, matlab 14 posts — sections se ek zyada kyunki open run ke dono ends par post chahiye.
Kaunsi post spacing use karein?
Prefab panels wali privacy fence ke liye 2.4 m (8 ft) standard hai; windy areas ya heavy boards ke saath 1.8 m fence ko zyada rigid banata hai.
Har post mein kitna concrete lagta hai?
Ek typical 9×9 cm post, 20 cm hole mein 60 cm deep, kareeb 0.5 cubic feet concrete leta hai — lagbhag 1.5 bags 50-lb ke. Total whole bags tak round hota hai.
Gates material kaise badalte hain?
Wo do posts ke beech ek section leते hain, apne rails-pickets nahin — wo gate kit ke saath aate hain. Gate posts ko strong rakhna aur zyada gehra gaadna common practice hai.
