Three quarters of a cup is one of the most common amounts in baking, and 3/4 cup of rice flour is about 106.5 g on the scale. The figure comes from King Arthur Baking's full-cup value of 142 g, spooned and levelled, multiplied by three quarters.

All figures are approximate. One US cup of rice flour weighs 142 g spooned and levelled (King Arthur Baking), and every fraction above is calculated from that figure. When the result matters — a cake, a loaf, a sauce you cannot remake — verify with a kitchen scale.
When 3/4 cup of rice flour matters most
3/4 cup of rice flour turns up most often in scaled-down recipes, single-serving bakes, and recipes written for two people instead of four. It is also the amount you reach for when you are halving a recipe that originally called for half a cup, or quartering one that called for a full cup. Gluten-free blends, shortbread and tempura batter. In those situations the amount is small but the stakes are not: a halved recipe has less margin for error, so a heavy-handed 3/4 cup can throw the whole balance off. Weighing the 106.5 g instead of eyeballing it is the simplest insurance you can buy for a small batch.
Worked examples
Example 1: a small batch of gluten-free blends
You are making a small batch of gluten-free blends and the recipe lists 3/4 cup of rice flour. Instead of hunting for the right measuring cup, put the mixing bowl on the scale, tare it, and add rice flour until you reach 106.5 g. Because rice flour is finely ground white rice; a staple of gluten-free baking. this weight-first approach keeps the batch consistent even if you make it again next week.
Example 2: doubling from 3/4 cup to 1 1/2 cup
You liked the recipe and want to double it, so 3/4 cup becomes 1 1/2 cup. That is 213 g of rice flour. Weighing the doubled amount is easier than filling a 3/4 cup cup twice, because a second scoop rarely matches the first. One weighing of 213 g is both faster and more accurate.
Example 3: checking a recipe that seems off
If a cake comes out dense or a sauce comes out thin, the first suspect is the measuring. A recipe that asked for 3/4 cup of rice flour was written for about 106.5 g. If you scooped a packed cup instead, you may have added far more. Next time, weigh the 106.5 g and compare the result — it is the quickest way to find out whether the recipe or your measuring was at fault.
How 3/4 cup of rice flour is measured
The figure of 106.5 g is based on rice flour measured spooned and levelled, following King Arthur Baking. One full cup weighs 142 g under that method, and 3/4 cup is simply that figure multiplied by 0.75. That is why the headline number is labelled approximate: it is a calculation from a published full-cup density, not a measurement of the exact spoonful in your kitchen.
If your rice flour was measured differently, the weight changes. A scooped cup packs more in; a sifted cup holds less; a packed cup of a sticky ingredient holds far more than a spooned one. The method matters as much as the number, which is why every conversion on this site states its method alongside its source. When a recipe matters — a celebration cake, a loaf of bread you have been planning, a sauce you cannot remake — weigh the rice flour on a kitchen scale and let the scale settle the argument. 106.5 g is a good target; the scale tells you when you have actually hit it.
King Arthur Baking is the source for the full-cup figure, and this site uses that value consistently across every rice flour page, so the quarter-cup, half-cup and full-cup figures all agree with each other. If you have seen a different number elsewhere, it almost certainly comes from a different method or a different source's rounding — not from a different ingredient.
Practical guidance for rice flour
Gluten-free blends, shortbread and tempura batter. That range of uses is exactly why the weight matters: the same 3/4 cup of rice flour behaves differently in a cake batter, where it must hydrate evenly, than in a bread dough, where it builds gluten. Weighing 106.5 g gives the recipe the amount its author tested, whatever you are making.
Storage changes the number too. Airtight container, cool and dry, up to 1 year. Flour that has sat in a humid kitchen absorbs moisture and weighs more per cup; flour that has been in the freezer and brought out cold can clump. Keep it sealed, bring it to room temperature before baking, and spoon it loosely when you measure by volume.
The most common failure with rice flour is a dry, heavy bake caused by too much flour. If your cakes keep coming out dense, weigh the flour for a few bakes and compare with your usual cup measure — most bakers find they have been adding 10–20 g extra per cup without realising it. 3/4 cup at 106.5 g is a small enough amount that the error is easy to miss and large enough, proportionally, to matter.
Common mistakes with 3/4 cup of rice flour
Rounding the figure too aggressively. 106.5 g is already a rounded figure; rounding it again to 106 g is fine for most cooking, but for delicate baking keep the full figure.
Scooping the cup straight from the bag or jar. This packs rice flour down and can add 15–20% extra weight. Spoon it in loosely and level it off, or better, weigh it.
Using a liquid measuring jug for a dry ingredient (or the reverse). Dry cups and liquid jugs are not interchangeable, and the meniscus on a jug makes small dry amounts hard to read.
If you do not have a scale
Four level tablespoons are roughly 3/4 cup of a cup — about 106.5 g of rice flour. Tablespoons are easier to level accurately than a small cup, so this is a decent fallback.
If you only have a 1-cup measure, fill it to the 3/4 cup line and level it. Read it at eye level on a flat surface; reading from above makes the line look lower than it is.
For sticky or pourable rice flour, lightly oil the measure first so it releases cleanly, and pour slowly so you can stop at the line.
Remember that any of these fallbacks is approximate. A kitchen scale is inexpensive, and it turns every conversion on this site — including this 106.5 g figure — from a good guess into a measurement you can trust.
Frequently asked questions
What is the best way to store rice flour so the conversion stays accurate?
Airtight container, cool and dry, up to 1 year. Keeping rice flour dry and settled matters, because clumping and moisture change how much fits in a cup — and therefore how much a cup weighs.
Should I sift rice flour before measuring 3/4 cup?
Only if the recipe says to. Sifting adds air and lowers the weight per cup, so 3/4 cup of sifted rice flour weighs less than 3/4 cup measured spooned and levelled. The 106.5 g figure here assumes rice flour measured spooned and levelled, not sifted — unless your recipe explicitly says 'sifted'.
How many tablespoons is 3/4 cup of rice flour?
3/4 cup of a cup is four tablespoons by volume. By weight that is about 106.5 g of rice flour. Tablespoons are a useful fallback when you do not have a 3/4 cup measure, but weigh the result if you can, because a heaped tablespoon is not the same as a level one.
Why do different websites give different grams for 3/4 cup of rice flour?
Because the full-cup figure differs between sources. King Arthur Baking lists 142 g per cup spooned and levelled, and other sources may scoop, pack or sift differently. Packing, brand and humidity all shift the true density a little, and different sources round their figures differently. The differences are usually small for 3/4 cup, but they explain why you see several figures online.
How do I measure 3/4 cup of rice flour without a scale?
Use a 3/4 cup measure and the spooned and levelled method: spoon the rice flour in loosely, level the top with a straight edge, and do not pack it down. Four level tablespoons are the same volume. Expect the result to be approximate, and use a scale for baking where precision matters.
