Sticky Rice Flour Converter

Why sticky rice flour isn't just "another flour"

Sticky rice flour — also labeled glutinous rice flour, sweet rice flour, or by its Thai name paeng khao niao — is milled from glutinous rice rather than wheat, and despite the name it contains no gluten at all. What makes it "sticky" is its starch composition: glutinous rice is almost entirely amylopectin, a branched starch molecule that gels into a soft, chewy, translucent texture when cooked, very different from the protein-based structure that makes wheat dough elastic. That's why it's the base for Thai and broader Southeast Asian sweets and dumplings that need a chewy bite — you can't substitute wheat flour or even regular (non-glutinous) rice flour and get the same result.

For measuring purposes, this converter uses 125 grams per cup as a practical middle figure, since reliable sources put sticky rice flour's weight per cup somewhere in a 120–130 gram range depending on the brand and, more significantly, on whether you scooped the flour directly from the bag (which packs it more densely) or spooned it in loosely and leveled it off. That range is narrower than an ingredient like palm sugar, so a single working number is reasonable here — but if your recipe states its own gram figure, follow that over this converter's default.

It's worth being clear that sticky rice flour is a distinct ingredient from the all-purpose, bread and cake flours covered on our Flour Grams to Cups Converter. The two converters happen to land on a similar weight-per-cup (120g for all-purpose flour versus 125g for sticky rice flour), but that's a coincidence of density, not a sign the ingredients behave the same way in a recipe — they are not interchangeable.

Where sticky rice flour shows up in Thai desserts

• Mango Sticky Rice-style desserts — note that the classic dish itself uses whole glutinous rice grains, not the flour; sticky rice flour instead shows up in related Thai sweets and dumplings often served alongside mango and coconut milk, where a chewy, moldable dough is needed rather than cooked whole grains.

If your recipe calls for whole glutinous rice rather than the milled flour, this converter isn't the right tool — the two are prepared completely differently.

Frequently asked questions

How much does 1 cup of sticky (glutinous) rice flour weigh?

About 125 grams is a reliable working average, though it can range from roughly 120 to 130 grams depending on the brand and how firmly the flour was packed into the cup.

Is sticky rice flour the same as regular rice flour or all-purpose flour?

No. Sticky (glutinous) rice flour is milled from glutinous rice, which is almost entirely amylopectin starch — that's what gives it a chewy, sticky texture once cooked. Regular rice flour comes from non-glutinous rice and behaves quite differently, and wheat flour relies on gluten rather than starch structure entirely. The weight per cup happens to land close to all-purpose wheat flour, but the two aren't interchangeable in a recipe.

Why is the weight given as a range (120-130g) instead of one number?

Scooping the flour directly from the bag (dip-and-sweep) packs it more densely than spooning it in loosely and leveling off, and that alone can shift the weight by 10-15%. Brand and how finely the flour is milled add a little more variance on top, which is why this converter uses 125g as a practical middle figure rather than pretending there's one exact number.
