How Many Calories Are In Watermelon? | Sweet Facts Fast

Watermelon Calorie Count By Portion (Quick Chart)

Here’s the bite-size answer by common servings. The numbers below use raw, seedless flesh. They round to the nearest whole where helpful.

Portion	Calories	Notes
1 cup, diced (152 g)	46	Go-to reference for meal logging.
100 g	30	Handy for metric recipes and labels.
1 wedge (≈1/16 melon, ~286 g)	~86	Party slice; double the cup size.
10 melon balls (~122 g)	~37	Fun in fruit salads.
1 small bowl (2 cups)	~92	Light dessert, big volume.

Most people snack by the bowl or the wedge. A quick way to estimate: one heaping cup lands near 50 calories. Bigger slices just scale from there.

What Shapes The Calorie Number

Two levers move the math: serving size and water content. The fruit is mostly fluid with a modest carb load. That’s why you can eat a large bowl without stacking calories.

Serving Size And Cut Style

Cubes pack tighter than balls. A wedge is lighter per volume than a tight dice. If you like precision, weigh a sample once and save that typical weight for your tracker.

Water Content And Sugar Balance

The flesh carries roughly nine to ten grams of sugar per cup with trace fiber and protein. Plenty of water offsets energy density, so the calorie count stays low even when the portion looks large. You’ll also get vitamin C and a touch of vitamin A alongside that sweet bite. Data for these figures come from federal nutrition tables and lab-analyzed entries that list the same 46-calorie benchmark per cup.

Set hydration goals first and snacks fall into place. Many readers find it easier to meet daily fluids when juicy fruits pitch in, which makes sense since public-health pages explain that foods count toward total fluid intake. water & healthy drinks is a plain-language reference for that idea.

Calories By Common Uses

Snack Bowls

Two cups after a summer walk? Call it about 90 to 95 calories. Add a pinch of salt and a squeeze of lime to perk up the flavor if you’re sweaty from a workout.

Smoothies And Slushes

Blend one cup of fruit with one cup of ice and a few mint leaves. That’s still near 50 calories for the fruit, plus zero for the ice. If you splash in yogurt or juice, add those calories separately.

Salads And Savory Plates

Cube one cup and toss with cucumber, feta, and olives. The fruit contributes ~46 calories; the cheese and oil do the heavy lifting. Measure those add-ins to keep the dish aligned with your plan. For a deeper primer on daily intake math, snacks fit better once you set your daily calorie needs.

Nutrition Snapshot Beyond Calories

Macronutrients Per Cup

Per cup, you’re looking at ~11.5 g carbs, ~0.9 g protein, and ~0.2 g fat. Sodium sits near 1–2 mg. It’s a low-energy food with a refreshing feel.

Hydration Angle

With roughly ninety-plus percent water, this fruit can help cover fluids alongside a bottle of water. Public-health pages note that foods with high water content contribute to your total intake, which is handy on hot days or after training.

Color Compounds

The pink hue signals carotenoids such as lycopene. Research catalogues this pigment widely in the fruit. It’s part of the broader nutrient story, even though calories stay low.

Portion Guide You Can Use All Year

Everyday Tracking Tips

Pick one method and stick to it. If you log by cups, always pack your measuring cup the same way. If you log by weight, use the 30-calories-per-100-grams shortcut and you’ll be in the right ballpark.

Entertaining And Family Plates

For crowd trays, wedges are faster. A typical wedge near 286 g lands around 86 calories. Build platters with a mix of salty and creamy sides so the fruit’s low-calorie volume carries the dish.

Post-Workout Refuel

Two cups of cubes plus a pinch of salt helps with fluids and a small carb bump. Add a protein on the side if you’re lifting. See our take on high-protein breakfast ideas for pairings that travel well.

Is The Calorie Count The Same For All Types?

Seedless vs. seeded makes little difference for energy per cup. Yellow or orange flesh may shift carotenoids, not calories. Your portion size and how tightly the cup is packed will move the number far more than variety.

How This Compares With Other Juicy Fruits

You’ll see similar energy in strawberries and a bump in cantaloupe. Grapes and mango move higher. The shared thread is water content: the more fluid on the plate, the lower the energy density tends to be. Nutrition databases list these patterns consistently.

Serving	Typical Weight	Estimated Calories
1 cup, diced	152 g	46
1 wedge (1/16 melon)	~286 g	~86
100 g	100 g	30
2 cups, diced	~304 g	~92
10 melon balls	~122 g	~37

Smart Ways To Build A Snack Around It

Keep It Cold

Chilled fruit tastes sweeter, which helps small portions feel satisfying. Pre-cube a batch and store it in clear containers so it’s the first thing you grab.

Add Texture

Pair with roasted nuts or a sprinkle of seeds for crunch. The fruit covers volume and fluids; the garnish brings a little protein and fat. Measure mix-ins if you’re tracking tightly.

Season It

Mint, lime, chili powder, and flaky salt turn a simple bowl into a bright plate. Seasonings are near-zero calories, so they’re an easy win for flavor.

Calories In Whole Melons And Big Trays

Database entries list a whole 15-inch melon near 1.3–1.4k calories based on typical weights. That sounds big until you divide the tray into cups and wedges for a picnic. Track by serving and the math gets friendly fast.

Evidence And Sources For The Numbers

Primary Databases

The calorie line in this guide is anchored to lab-referenced records that list 46 calories per cup and ~30 per 100 grams along with water near ninety-plus percent. You can see those figures in the USDA’s public pages and in database tools that draw directly from them.

Hydration Context

Public-health pages explain that foods contribute to total water intake, which supports using juicy fruit as part of your daily fluids plan. A clear overview sits here: water & healthy drinks.

Practical Takeaway For Meal Planning

If you like clean numbers, anchor snacks to 1–2 cups. Log 46 calories per cup, 30 per 100 grams, and ~86 for a generous wedge. Build plates with protein on the side when you need staying power.

If you prefer hydration cues, plan fruit portions around your fluid target. Public-health definitions make it clear that food water counts toward the daily total, so a cold bowl of cubes can help you hit the mark on a hot day.
