How Many Calories Are There In A Cucumber? | Crisp Facts

Cucumber calories are tiny, which is why they show up in salads, wraps, and snack plates. The trick is knowing how much energy you get from a cup of slices, a whole long one, or a peeled version. This guide gives clear numbers, quick conversions, and handy tips for tracking portions at home.

Cucumber Calories By Portion

Here are the most common kitchen portions with plain, raw cucumbers. Values align with standard nutrient references and round to the nearest whole number for easy planning.

Portion	Typical Weight	Calories
100 g, with peel	100 g	15 kcal
1 cup slices	~104 g	16 kcal
1/2 cup slices	~52 g	8 kcal
1 English half (seedless)	~170 g	26 kcal
1 small, whole	~120 g	18 kcal
1 medium, whole (8–9 in)	~300 g	45 kcal

These counts snap into place once you know your daily calorie intake, since cucumbers usually add volume, not energy.

Cucumber Calories Per 100 Grams (And How To Measure)

Per 100 grams, raw cucumbers with the peel land near 15 calories. That’s a handy anchor for meal builders: weigh once, learn the look, and you can judge slices by eye next time. If you’d rather use cups, a level cup of thin slices weighs close to 104 grams, which comes to about 16 calories. A heaping cup adds a few grams, so the change stays small.

Peeling barely changes calories because most of the energy comes from water-rich flesh. The skin brings a touch of fiber and a bit of shade to the number. Salt, dressings, or dips are what move the needle, not the cucumber itself.

For a deeper nutrient breakdown, see the MyFoodData cucumber profile, which compiles USDA FoodData Central entries and lists water content, carbs, and minerals by portion.

What Changes The Count?

Two things change energy: the flavorings you add and whether liquid is trapped or drained. A sprinkle of salt pulls water, which softens slices. That doesn’t raise calories by itself, yet any oil, ranch, mayo, or cream cheese will. Even a light spread can match the cucumber’s calories several times over, so measure dips with a spoon instead of eyeballing the bowl.

Pickled versions stay low in energy, though sodium can climb fast depending on the brine. Sweet pickles pick up sugar, while fresh dill spears stay lean. If you’re tracking carbs closely, check the jar’s label and choose brines without added sugar.

Weighing, Scooping, Or Counting?

Home cooks usually pick one method and stick with it. If you own a scale, weigh 100 grams once and see what that looks like in your favorite bowl. If you prefer scoops, note that a level cup of slices sits near 16 calories; half a cup lands near 8. Whole-cucumber counting works too: small, medium, and long seedless styles rarely break 50 calories each.

Food labels use standard serving sizes so shoppers can compare like with like. In the United States, raw produce uses reference amounts that help set those labels. You’ll see calories listed per serving and per 100 grams to make swaps easier. See the FDA’s RACC standard for the labeling principle that underpins those servings.

Nutrition Snapshot Beyond Calories

Energy is only part of the story. Cucumbers are mostly water—around ninety-five percent—which helps with fluid targets on hot, humid days. The rest is a small mix of carbohydrate, a trace of protein, and nearly no fat. You’ll get a light hit of vitamin K and potassium, though not a large share of daily needs. That’s why they pair well with protein and grains: the plate stays light while volume and crunch go up.

If you need even less energy per bite, peeled slices drop a hair lower. If you want a bit more fiber, keep the peel on and cut thicker rounds. Both work fine in salads; the choice is texture.

Simple Ways To Use More Cucumber Without Extra Calories

Salad Upgrades That Stay Light

Swap half of the pasta or grains in cold salads with equal volume of chopped cucumber. You keep the bowl size, trim the energy, and the dressing stretches further. Add lemon juice or vinegar before oil so the bright flavor means you need less fat to feel satisfied.

Crunchy Snacks With A Plan

Make a tray of rounds topped with a skim of Greek yogurt and herbs. Pre-portion the yogurt in a small dish so the add-on calories stay predictable. A twist of pepper and a few seeds pull the snack together without denting your budget.

Hydration Boosters

Add long ribbons to water bottles, or stir them into salsas with lime and jalapeño. The flavor is clean and the energy cost is near zero.

Calories By Style (Peeled, Unpeeled, Pickled)

Numbers below refer to typical portions you’ll see in recipes and labels. Sodium varies widely in pickles; check the jar.

Item	Serving	Calories & Notes
Raw, with peel	100 g	~15 kcal; ~95% water
Raw, peeled	100 g	~12–14 kcal; slightly less fiber
Dill pickle spear	1 spear	~4–7 kcal; sodium can be high
Sweet pickle chips	10 chips	~35–50 kcal; added sugar
English (seedless)	1 cup slices	~14–16 kcal; mild flavor

How To Estimate Without A Scale

Hand cues help when you’re eating out. A handful of thin slices is close to half a cup, about 8 calories. A palm-sized stack is near a full cup, about 16 calories. A long seedless half weighs near 170 grams, close to 26 calories. Even a full large one stays near the 45-calorie mark.

Once you’ve eyeballed a few plates, the guesswork fades. Keep dressings on the side, taste first, and add a measured drizzle if you need more richness.

Cooking Methods And Add-Ons

Salted And Drained

Salting draws water, softens texture, and concentrates flavor. Energy per gram ticks up a touch as water leaves, yet the total for the bowl stays almost the same unless you pour in extra oil afterward.

Quick Pickles

Vinegar, spices, and fresh garlic keep energy low. Sweet brines add calories; labels will show the difference. If sodium intake is a concern, choose lower-sodium recipes or rinse lightly before serving.

Grilled Or Stir-Fried

Warm cucumbers bring a tender snap. Use a hot pan, brief heat, and a measured teaspoon of oil. The heat keeps them bright and the energy budget steady.

Smart Pairings To Build A Meal

Since cucumbers are energy-light, pair them with foods that carry protein and fiber. Think canned tuna with lemon and dill, chickpeas with chili flakes, or quinoa with mint and feta. These matchups bring staying power while the cucumber adds moisture and crunch.

If you’re watching sodium, lean on herbs, citrus, and vinegar. If carbs are your focus, keep sugary dressings off the plate and use plain yogurt or tahini to add body without a spike.

Bottom Line On Cucumber Calories

You get roughly 15 calories per 100 grams, 16 per cup of slices, and under 50 for most single whole ones. That makes cucumbers an easy way to bulk up meals without bulking up energy. Keep an eye on oils and sweet brines, and you can enjoy generous portions any day.
