How Much Dor Do You Need for One Day of Basant? The Consumption Math Nobody Publishes

• Baseline: ~2 pieces per casual flyer per full day; ~4 for aggressive duellists
• Cuts are the multiplier — you lose line in every defeat, and sometimes in victory
• One ball on the roof is a problem: parallel charkhis keep the flying continuous
• Three festival days ≠ 3× one day; days two and three run lighter for most groups
• Under-buying costs more than over-buying: mid-festival dor is the season's most expensive

Every rooftop asks this question exactly once — usually at 11am on the festival's first day, holding an empty charkhi. How much dor you need isn't mystical; it's arithmetic driven by two numbers (flyers and flying style) and one multiplier (how many duels you lose). Here's the worksheet, from a shop that spends the season hearing which estimates survived contact with the sky. It pairs with our dor price guide — this page is *how many pieces*, that one is *what they cost*.

Why does kite flying consume so much line?

Because line, unlike kites, disappears in chunks. Three drains run all day:

• Cuts. Lose a pecha and everything past the cut point goes with the kite — often several hundred yards in one moment.
• Damage. Cotton frays at rub points and tangles cost usable length even when untangled.
• Working length. A high, steady kite holds 400–800 yards aloft continuously; you can't fly nine kites off one 2,000-yard ball even with zero losses.

That first drain dominates. A flyer who avoids duels can nurse 2 pieces all day; a flyer hunting bo kata converts line into glory at a rate that surprises first-timers.

The worksheet: pieces by rooftop

Baseline assumptions: full main-day flying, legal 9-ply cotton in 1,000-yard pieces, a mix of gudda and patang.

Round up, not down, for three reasons: spare line rescues a good day (a fresh ball mid-afternoon keeps the roof flying), leftover cotton keeps perfectly for the next window, and the alternative — buying mid-festival — means the week's worst prices *if* stock exists. In 2026's one-week retail window, the city cleared shelves before the festival ended.

Does three festival days mean three times the dor?

No — plan the main day fully and scale the rest. Most rooftops fly hardest on one headline day (2026's middle Saturday was the peak), with lighter sessions either side. A working rule: main day at full worksheet rate, plus 50–60% of that total to cover the other two days. The 4-flyer roof planning 10 main-day pieces books 16 for the festival and comes home right.

Night sessions consume less than daytime duels — fewer crossings, steadier flying — but they still eat working length, so the white-kite hours aren't free.

How should the pieces be split across balls?

Favor more balls over bigger ones, up to a point. Two flyers sharing one 6-piece ball take turns; two flyers with a 2-piece and a 4-piece fly simultaneously. Parallel charkhis are what keep a rooftop's sky continuously occupied — and a cut becomes a two-minute reload instead of a queue.

Mixing names works fine too: many groups run a premium ball (8 Chain or Air Blade) for the serious duellist and entry-name balls for everyone else. Same legal cotton throughout; the split is about feel and budget, not legality.

Do the math once, fly all day

Count your flyers, tag your duellists, read the table, round up — done. Then reserve the pieces free or price-locked, and spend the festival watching the sky instead of the supply.
