The carb count in 100 grams of rice depends on whether the rice is cooked or dry. That’s the biggest point most people miss when they try to track it.
As a practical rule, 100 grams of cooked rice usually contains about 23 to 28 grams of carbs, while 100 grams of dry rice is much higher because it has not absorbed water yet. Use the steps below to estimate your portion correctly.
1. First, check whether the rice is cooked or dry
If you only remember one thing, make it this: cooked rice and uncooked rice are not interchangeable by weight. Water changes the weight a lot, but it does not add carbs.
For most common types, 100 grams of cooked white rice is roughly 28 grams of carbs, and 100 grams of cooked brown rice is often around 23 grams of carbs. By contrast, 100 grams of dry white rice can be around 80 grams of carbs before cooking.
If you are logging food from a meal photo, Fitnit’s meal tracking can help you estimate portions more consistently, but the label or recipe method still matters when rice is a main ingredient.
2. Use the rice type to narrow the estimate
White rice, brown rice, jasmine rice, and basmati rice all land in a similar carb range, but exact numbers vary by variety and cooking method. Long-grain and short-grain rice can differ a little, and brown rice usually has slightly more fiber than white rice.
For a quick estimate, use these practical ranges for 100 grams cooked: white rice about 28 grams of carbs, brown rice about 23 grams, and wild rice or rice blends can vary more. If the rice is dry, the carb number will be much higher per 100 grams.
If you need an exact number for tracking, check the package nutrition panel or USDA food data for the specific rice you ate.
3. Weigh the rice the right way
Use a kitchen scale if you can. Place the rice in a bowl, note whether it is cooked or dry, and weigh it after preparing it the same way you plan to log it.
If you cook a batch for meal prep, weigh the finished rice after cooking and divide it into portions. That makes your carb tracking much easier than trying to guess by cups.
If you do not have a scale, measure consistently with a cup, but remember that cup measures are less precise because rice can be packed loosely or tightly.
4. Avoid the most common mistakes
The biggest mistake is using the dry-rice carb number for cooked rice, or the other way around. That can throw off your total by a large amount.
Another common mistake is assuming all rice has the same carb count. Sauced rice dishes, fried rice, and rice mixes often include oil, sugar, or other ingredients that change the nutrition profile.
Do not forget serving size. If you eat 200 grams of cooked rice, double the 100-gram estimate. If you eat a smaller side portion, scale it down accordingly.
Tips
- Always label your portion as cooked or dry before you log carbs.
- For meal prep, weigh the cooked rice once, then divide it into equal containers.
- Use a food scale for the best accuracy, especially if you track macros closely.
- Check the nutrition label or USDA data for the exact rice variety when precision matters.
- If you track workouts too, consistent meal logging and form feedback can help support your overall goals.

Frequently Asked Questions
How many carbs are in 100 grams of cooked rice?
Usually about 23 to 28 grams, depending on the rice type.
How many carbs are in 100 grams of uncooked rice?
Often around 75 to 80 grams of carbs, depending on the variety.
Does brown rice have fewer carbs than white rice?
Slightly, in many cases. Brown rice often has a bit less net starch and more fiber, but the difference is not huge.
Why is the carb count different after cooking?
Cooking adds water, which increases the weight but does not add carbs. That lowers the carbs per 100 grams.
