Calories In Half A Cucumber By Size
Most calorie calculators use the 100-gram baseline. With the peel, cucumber sits near ~15 kcal per 100 g; peeled slides to ~12 kcal per 100 g. Those figures come from datasets that compile lab results and survey portions. You can view the exact nutrient panel on MyFoodData, which echoes USDA FoodData Central values.
Now to real-world halves. A half isn’t a fixed unit, so we map common sizes and a simple formula. Weight varies by variety and length. A classic field type in the 7–8¼-inch range lands near 280–320 g for the whole thing, while the long seedless style tends to be lighter per inch but longer overall. Ranges below keep it practical for kitchen use.
Typical Half Cucumber Calories
| Size / Type | Approx. Half Weight | Calories (Peel On / Peeled) |
|---|---|---|
| Small field type (6–7 in) | 100–130 g | 15–20 kcal / 12–16 kcal |
| Medium field type (7–8¼ in) | 140–170 g | 21–26 kcal / 17–20 kcal |
| Large field type (8¼–9+ in) | 170–200 g | 26–30 kcal / 20–24 kcal |
| Long seedless (English) | 160–190 g | 24–29 kcal / 19–23 kcal |
| ½ cup slices (reference) | ≈50–60 g | 7–9 kcal / 6–7 kcal |
These bands come from two pieces: the 100-gram energy value and the usual weight of a half. For portion context, a half-cup of thin slices runs about the weight shown above, which lines up with common nutrition panels for chopped veg portions.
Once you’ve sketched your day’s numbers, snacks land better when you’ve set your daily calorie needs. That way a half cucumber can plug holes without pushing totals.
How To Estimate Your Half Quickly
Grab a plate and a scale if you have one. No scale? Use quick cues: a tight-fisted handful of slices weighs about 50–60 g; a tall stack from half a medium field type sits closer to 140–170 g. Multiply grams by 0.15 for peel-on calories or by 0.12 for peeled. That’s it.
Peel On Or Off?
Peel adds a smidge more energy along with fiber and a trace of vitamin K. With peel you’re using ~15 kcal per 100 g; without peel you’re closer to ~12 kcal per 100 g. Both are slim. The difference across a half rarely breaks 4–6 kcal for common sizes. You can verify the with-peel and peeled panels on MyFoodData for with peel and peeled.
Why Sizes Vary So Much
Growers ship ranges, and labels don’t always promise a weight. Trade specs set minimums, not exact sizes. The USDA grading pages describe lengths such as 6 inches or longer for certain lots. If you like numbers, see the USDA cucumber grades page for minimum length notes. In the kitchen, measure the half you’ve got, not the one on a chart.
Portion Math You Can Trust
Here’s a simple way to keep your counts tight without scraping decimal dust.
Quick Formula
Peel on: grams × 0.15 = calories.
Peeled: grams × 0.12 = calories.
Say your half comes in at 160 g on the scale. Peel on math gives ~24 kcal. If you use a veggie peeler first, you’ll land nearer ~19 kcal.
Common Prep Tweaks That Change The Count
- Salted and drained: water loss barely moves calories; it just concentrates weight a touch.
- Oil drizzle: 1 teaspoon oil adds about 40 kcal. That dwarfs the cucumber itself.
- Yogurt dip: 2 tablespoons of plain Greek yogurt adds ~20–30 kcal and a bit of protein.
Where Half A Cucumber Fits In A Meal
Low energy, high water, light crunch—handy when you want volume with little calorie load. Pair with protein at lunch, add to grain bowls, or layer into sandwiches. The peel brings texture and fiber. Peeled slices suit kids and mild palates.
Smart Pairings
- Protein plate: chicken breast, half a cucumber, cherry tomatoes, and a spoon of hummus.
- Grain bowl: quinoa, diced half, feta, olives, and a squeeze of lemon.
- Snack box: baton cuts, yogurt dip, and a few almonds.
Calorie Ranges For Popular Servings
Use these as checkpoints when you don’t want to weigh. Values assume peel on unless noted.
Serving Cheatsheet
| Serving | Approx. Weight | Calories |
|---|---|---|
| ½ cup slices | 50–60 g | 7–9 kcal |
| 1 cup slices | 100–120 g | 15–18 kcal |
| Half, small field type | 100–130 g | 15–20 kcal |
| Half, medium field type | 140–170 g | 21–26 kcal |
| Half, long seedless | 160–190 g | 24–29 kcal |
| Half, peeled (medium) | 140–170 g | 17–20 kcal |
Hydration, Micronutrients, And Fiber
Water content sits above 95%, which helps meals feel bigger for very few calories. You’ll pick up small amounts of vitamin K, vitamin C, and potassium. That’s one reason summer salads feel light yet satisfying. For plain nutrient panels, see the MyFoodData cucumber page linked earlier.
Peel, Seeds, And Texture
Peel gives bite and a trace of fiber. Seeds add little to energy but do change texture. If bitterness pops up, a quick strip of the outermost peel band can help while keeping most of the crunch.
Buying And Storing For Best Results
Pick firm, glossy skins with no soft spots. If you buy long seedless types, keep the wrapper until use to limit moisture loss. Store in the crisper drawer and use within a few days. Dry slices before dressing so oil coats evenly; wet surfaces make dressings slide off and pool.
Make Your Counts Stick Day To Day
Habits win here. Keep half prepped in the fridge for easy grabs. Add a dash of acid—lemon or vinegar—so you reach for it more often. A tiny sprinkle of flaky salt right before eating wakes up the flavor without changing energy meaningfully.
FAQ-Free Final Notes
Half a medium field type with peel lands close to 22–25 kcal. Peeled trims a few calories but also loses a touch of fiber. When in doubt, weigh once, do the quick math, and you’re set for repeat buys from the same store. Calorie math doesn’t need to be fussy to be reliable.
