The single most confusing thing about ordering durian online is durian box size. You see a 600g box on one page and a whole fruit priced by the kilogram on another, and the two numbers refuse to line up. They are not supposed to. A box holds pulp only — the flesh, already lifted off the husk and the seed — while a whole durian is sold with everything still attached. One Singapore delivery listing puts the conversion in plain sight: a 600g package of pure durian pulp is taken from roughly 2.55kg of whole durian, husk included. An 800g package comes from about 3.4kg.
Once you have that ratio, a lot of durian pricing stops looking arbitrary.
The husk is most of the fruit
Roughly a quarter of a whole durian's weight ends up on your plate. The rest is husk — thick, spiked, heavy, and worth nothing once the fruit is opened. Seeds take another share, which is why growers and sellers talk so much about seed size. When a listing describes a variety as having small seeds and more meat, that is not a flavour note. It is a yield claim: the same weight of whole fruit gives you more edible flesh.
That is the arithmetic behind every dehusked box. A vendor buys whole fruit, opens it, discards the husk, and packs what survives. When you buy a box, you are buying the part that made it through, plus the labour of getting it there and the risk the vendor took on fruit that opened badly.
Reading a box against a whole-fruit price
Compare like for like. If you are looking at a whole durian, multiply the weight by roughly one quarter to estimate the pulp inside. A 2.5kg fruit lands you somewhere near a 600g box. A 3.4kg fruit is in 800g territory. This is an estimate, not a guarantee — yield swings with variety, ripeness, and how cleanly the fruit is opened — but it is close enough to stop you concluding that boxed durian is a rip-off when it is simply a different unit of measurement.
The trade-off is real either way. Whole fruit rewards you with the opening ritual, the smell as the husk splits, and the chance to see exactly what you bought before anyone touches it. A box removes the guesswork on quantity, the mess, and the problem of having no idea how to open a durian without wrecking your hands.
How to choose a durian box size for your group
The sellers who publish yield figures usually publish serving guidance alongside them, and it is sensible. A 600g box suits one to two people. An 800g box suits two to three. Those numbers assume durian is the event, not a garnish at the end of a full meal.
A few adjustments worth making:
- First-timers eat less than you think. Rich, custardy varieties fill people fast. If half your group is new to durian, size down.
- Mixed varieties beat one big box. Two smaller boxes of different varieties give a group something to compare and argue about, which is most of the fun.
- Durian does not keep well. Buy for the sitting, not for the week. Leftover pulp goes into the freezer within hours, not the fridge for tomorrow.
- Season matters more than size. In a heavy harvest year, more fruit reaches the market and more of it is good. That is the moment to try a variety you have been putting off.
What the ratio does not tell you
Yield is a measure of quantity, never of quality. Two boxes with identical weights can be entirely different experiences depending on the variety, the tree, and how long ago the fruit dropped. The number tells you how much you are getting. It says nothing about whether the flesh is bitter-forward or sweet and creamy, whether it is dense or watery, or whether it was opened this morning or two days ago.
So use the ratio for what it is good for: sanity-checking a price and sizing an order. Then choose on variety and on the seller's handling — how soon after opening the pulp is packed, and how quickly it reaches your door.
If you want that decision made simpler, DurianSupplier.com lists box sizes with the variety and the serving guidance together, so you can pick what fits your table before you pick what fits your taste. Ask us if you are unsure which size suits your group — it is a question we would rather answer before the order than after.
