How Many Calories Are In An Orange? | What The USDA Says

You grab an orange from the fruit bowl expecting a quick, healthy bite. The calorie count probably isn’t your first question — but it’s a common one. And the answer isn’t quite as simple as a single number.

Size, variety, and whether you’re eating the whole fruit or just the sections all shift the total. Here’s what the official nutrition data shows, so you can confidently track your intake without peeling back too much science.

Calories In One Orange: It Depends On The Size

The most reliable calorie figure comes from the USDA’s standard medium orange: about 2-5/8 inches in diameter, weighing around 131 grams. That single fruit clocks in at 62 calories, according to the agency’s nutrition database as of 2025.

The California Department of Education lists a similar size (4.96 ounces) at 69 calories as of 2025 — a small difference that reflects natural variation in fruit weight and variety. A large orange, roughly 3.1 inches across, runs about 86 calories per fruit as of 2025.

If you prefer measuring by the cup, One cup of raw orange sections delivers about 85 calories as of 2025. The takeaway? A typical orange fits easily into most daily calorie budgets without much calculation.

Orange Size / Serving	Approximate Weight	Calories
Small (about 2.3 inches)	~96 g	~45–50
Medium (2.6 inches, USDA standard)	131 g	62
Medium (CDE standard)	4.96 oz (141 g)	69
Large (3.1 inches)	~184 g	86
One cup of orange sections	~180 g	85

The range is tight enough that you can count a medium orange as about 65 calories and be within a reasonable margin of error for most diet-tracking needs.

Why The Calorie Count Can Surprise You

Oranges are mostly water — about 86% by weight — which is why the calorie density is so low. But several factors can make people think they’re eating more or fewer calories than they really are.

• Size variation even within “medium”: A grocery-store orange labeled medium can vary by 10–15 grams, shifting the calorie total by 5–10 calories. Two oranges from the same bag can differ noticeably.
• Variety differences: Navel oranges tend to be larger and slightly sweeter than Valencias, while mandarins and Cuties are smaller and often come in at 35–50 calories each. The USDA data covers generic “all commercial varieties.”
• Peeled vs. unpeeled weight: The calorie figures above are for edible flesh only. If you weigh a whole orange with peel, you’ll overestimate the calorie content — the peel adds about 30–40% extra weight with no calories.
• Orange sections vs. juice: A cup of orange sections (85 calories) is quite different from a cup of orange juice (about 112 calories). The whole fruit’s fiber also blunts the sugar impact.

The main point: if you’re counting calories from an orange, go by the fruit’s diameter or use a standard medium estimate rather than guessing from weight with the peel on.

Orange Nutrition Beyond Calories

A medium orange brings more to the table than just low calories. One fruit provides about 70 mg of vitamin C — that’s 78% of the daily value for men and 93% for women, per NutriScan data as of 2025. It also delivers 3 grams of dietary fiber, which supports digestion and helps stabilize blood sugar.

The carbohydrate profile matters too: a medium orange contains roughly 15 grams of total carbs, including about 12 grams of natural sugar. The fiber slows absorption, making it a better choice than fruit juice for blood sugar control. For a full breakdown of the official guidelines, see the USDA orange nutrition page.

You also get small amounts of vitamin A (about 4% DV), potassium, and folate. And with zero fat and zero sodium, an orange fits nearly any dietary pattern — from low-fat to heart-healthy to general weight management.

Nutrient	Amount Per Medium Orange (131g)
Calories	62
Carbohydrates	14.8 g
Fiber	3.1 g
Sugar	12 g
Protein	1.3 g

Compared to many processed snacks, an orange delivers a nutrient-to-calorie ratio that’s hard to beat — you get satiety from fiber and water, plus a meaningful dose of vitamin C, all for under 70 calories.

How Oranges Compare To Other Common Snacks

Putting orange calories in context helps you make better snack choices. Here’s how a medium orange stacks up against other popular options, based on standard serving sizes.

1. Orange vs. apple: A medium apple (about 182g) has roughly 95 calories — about 30 more than an orange. Both provide similar fiber, but the apple is slightly more calorie-dense.
2. Orange vs. banana: A medium banana (118g) delivers about 105 calories, nearly double the orange. Bananas also have more carbs and sugar, making the orange a leaner choice for weight-conscious diets.
3. Orange vs. orange juice: One cup of OJ (8 oz) contains about 112 calories and no fiber. The whole orange is more filling and metabolically gentler — a key reason the British Heart Foundation recommends the whole fruit over juice.
4. Orange vs. a handful of almonds: About 23 almonds provide roughly 160 calories, plus healthy fats and protein. Oranges are much lower in calories but also lower in protein and fat, so they work better as a light refreshment than a meal.

The comparison shows that an orange is among the lowest-calorie fruit options — only berries (like strawberries at about 50 calories per cup) are typically leaner. For a sweet, hydrating snack, it’s a smart pick.

Is The Sugar In Oranges A Concern?

The 12 grams of sugar in a medium orange raise questions for people watching their intake as of 2025. The good news is that whole-fruit sugar comes packaged with fiber, which slows digestion and prevents the rapid blood-sugar spikes that juice or refined sugars cause.

The california education orange data confirms that an orange’s natural sugars are paired with 3 grams of fiber and high water content. For most people, that’s about 3% of their daily sugar allowance — a far cry from the sugar in a candy bar or soda.

If you’re managing diabetes or prediabetes, the whole orange is generally considered a safe fruit choice, but it’s wise to pair it with a protein source (like a handful of nuts) to help support blood sugar management as part of a broader treatment plan. Two oranges a day is typically fine for most diets, but if you’re drinking juice from three oranges, you’re losing the fiber and concentrating the sugar.

The Bottom Line

A medium orange provides about 62–69 calories as of 2025, making it one of the lowest-calorie whole fruits you can eat. It also delivers a hefty dose of vitamin C, 3 grams of fiber, and 86% water content — all for under 70 calories. Counting oranges is simple: a medium fruit counts as roughly 65 calories, a large as about 85, and a cup of sections as 85.

If you’re watching your sugar intake or weighing portions for a specific meal plan, the peel adds significant weight without calories — weigh only the edible flesh for accuracy.
