Rice and noodles contain roughly the same amount of carbohydrates. A 200-gram cooked serving of white rice has about 60 grams of carbs, and the same amount of egg noodles or pasta also comes in at about 60 grams. The real differences show up when you look at the type of noodle, the variety of rice, and how your body processes the carbs in each.
Carbs Per Serving: A Close Match
Gram for gram, cooked white rice and cooked egg noodles or wheat pasta are nearly identical in carbohydrate content. For a typical 200-gram cooked portion, both deliver around 60 grams of carbs. That’s close enough that swapping one for the other won’t meaningfully change your carb intake.
Where things shift is when you move beyond plain white rice and standard egg noodles. Not all noodles are wheat-based, and not all rice is white. The specific varieties you choose can push the numbers apart.
How Different Noodle Types Compare
The word “noodles” covers a huge range of products, and their carb counts vary more than you might expect. Per 100 grams cooked, rice noodles contain about 25 grams of carbs, while udon noodles (made from wheat flour) come in slightly lower at around 22 grams. Egg noodles and standard wheat pasta fall in a similar range, typically 25 to 30 grams per 100 grams cooked.
Glass noodles (also called cellophane or bean thread noodles), made from mung bean or sweet potato starch, tend to be higher in carbs per serving because they’re almost pure starch with very little protein or fiber. Soba noodles, made partly from buckwheat, generally fall on the lower end of the carb spectrum and add a bit more protein and fiber than refined wheat noodles.
If you’re choosing noodles specifically to manage carbs, the type matters more than the broad category. A bowl of udon and a bowl of rice noodles look similar on the plate but differ by a few grams of carbs per serving.
Brown Rice vs. White Rice
Brown rice and white rice have similar total carb counts, typically within a gram or two of each other per serving. The difference is in fiber. Brown rice retains its bran layer, which adds about 2 to 3 grams of fiber per cooked cup compared to white rice. That extra fiber slows digestion slightly, which affects how quickly the carbs hit your bloodstream.
For people tracking net carbs (total carbs minus fiber), brown rice comes out a few grams lower. But the gap is modest enough that it won’t dramatically change a meal plan on its own.
Glycemic Index: How Your Body Responds
Total carb count tells you how much carbohydrate you’re eating. The glycemic index (GI) tells you how fast those carbs raise your blood sugar. This is where rice and noodles actually differ in a meaningful way.
White rice falls in the moderate GI range (56 to 69), meaning it raises blood sugar at a moderate pace. Wheat pasta like spaghetti has a low GI of around 42, according to Harvard Health Publishing. That’s a significant gap. The reason comes down to structure: pasta is made from dense semolina dough that your digestive enzymes break down more slowly than the soft, gelatinized starch in cooked rice.
This means that even though a plate of pasta and a plate of rice contain the same grams of carbs, the pasta will produce a slower, more gradual rise in blood sugar. For anyone managing blood sugar levels, this distinction matters more than the raw carb number. Cooking and cooling either food (then reheating it) also lowers the glycemic response slightly, because some of the starch converts to a form that resists digestion.
Protein and Fiber Differences
Beyond carbs, the nutritional profiles diverge. Egg noodles and wheat pasta contain more protein than white rice, typically 5 to 8 grams per cooked cup compared to about 4 grams for rice. That extra protein comes from the wheat gluten and, in egg noodles, from the egg itself. More protein in a meal helps slow carb absorption and keeps you fuller longer.
Fiber content varies widely depending on your choices. Regular white rice and refined wheat noodles are both low in fiber. Switching to whole wheat pasta bumps fiber up to around 6 grams per cup. Brown rice adds a couple of grams. Soba noodles made with a high percentage of buckwheat also offer more fiber than standard options. If you’re looking to get more from your carbs nutritionally, choosing a whole grain version of either rice or noodles makes a bigger impact than choosing one over the other.
Portion Size Is the Real Variable
Because rice and noodles are so close in carb density, the biggest factor in how many carbs end up on your plate is simply how much you serve yourself. Noodle dishes at restaurants often contain 300 to 400 grams of cooked noodles, which can push a single serving well past 75 grams of carbs. A large bowl of rice at a takeout spot can easily hit the same range.
Cooked rice and cooked noodles both roughly double in weight from their dry form due to water absorption. A common mistake when comparing nutrition labels is mixing up dry and cooked weights. If a package of dried noodles lists 70 grams of carbs per 100 grams, that number drops to around 25 to 30 grams once the noodles are boiled and have absorbed water. Always compare cooked-to-cooked or dry-to-dry to get an accurate picture.
