Cucumber nutrition by serving size
Every serving below is a USDA household measure for this food, a fraction of one, or a unit conversion. Amounts are USDA values scaled by weight; only the Nutrition Facts panel applies the coarser FDA label rounding.
| Serving | Weight | Calories | Total carbohydrate | Protein | Total fat | Dietary fiber | Total sugars |
|---|---|---|---|---|---|---|---|
| 1/2 cup slices | 52 g | 8 | 1.9 g | 0.3 g | 0.1 g | 0.3 g | 0.9 g |
| 1 cucumber (8-1/4") | 301 g | 45 | 10.9 g | 2 g | 0.3 g | 1.5 g | 5 g |

Cucumber types and what this USDA record covers
Most cucumbers in US stores fall into a few groups:
- Slicing cucumbers: the standard dark green cucumber with thick skin, often waxed to slow moisture loss. USDA's whole cucumber in the serving list is this type, about 8 inches long.
- English (hothouse) cucumbers: long, thin-skinned and nearly seedless, usually sold wrapped in plastic.
- Persian and mini cucumbers: short, thin-skinned and crisp, often eaten whole as a snack.
- Pickling cucumbers: short with bumpy skin, grown for brining.
USDA has no separate records for these types, so this page uses one record for all of them: raw cucumber with the peel. Because the types differ most in size, weighing the cucumber you use matters more than which type it is.
Peeled vs unpeeled cucumber nutrition
USDA analyzed peeled cucumber separately. Per 100 g, peeled cucumber has fewer calories and less than half the vitamin K of cucumber with the peel, so the dark skin carries much of the vitamin K. The numbers on this page are for unpeeled cucumber. If you peel a waxed slicing cucumber, as many cooks do, weigh it after peeling.
Pickling changes the numbers more than peeling does. A dill pickle soaks up salt from the brine, and USDA's dill pickle record has far more sodium than fresh cucumber's 2 mg per 100 g.

Labeling salads, dips and pickles made with cucumber
For a salad, dip or sandwich, weigh the cucumber as it goes into the product: peeled or unpeeled, and after seeding or squeezing if your recipe does that, since squeezed cucumber has lost water. Enter that weight with your other ingredients in the label generator. Pickles are harder: the cucumber absorbs part of the brine's salt and the rest is drained away, so a calculation from ingredients is only an estimate of sodium, and many pickle makers send finished product for lab analysis. The FDA reference amount for your product category is in the RACC lookup.
Cucumber nutrition label for Canada, the EU and the UK
The same serving of cucumber, drawn by the label formats other markets require: the Canadian bilingual Nutrition Facts table, the EU nutrition declaration (per 100 g, energy in kJ and kcal, salt instead of sodium) and the UK nutrition information table with reference intakes. The generator switches between these and many more from one recipe.

Frequently asked questions about cucumber
How many calories are in a whole cucumber?
A whole 8-1/4 inch cucumber (301 g) with the peel has 45 calories and 10.9 g of carbohydrate. Mini and Persian cucumbers are much smaller, so weigh them and enter the grams.
Why does cucumber have so few calories?
Cucumber is mostly water: 100 g of raw cucumber with the peel holds 95.2 g of it. That leaves little room for carbohydrate, protein and fat, the nutrients that supply calories.
Does cucumber have fiber?
Half a cup of sliced cucumber has 0.3 g of fiber, 1% of the Daily Value. That is below the 10% DV a serving needs for a "good source" claim.
Is a cucumber a fruit or a vegetable?
In botany it is a fruit: it grows from the cucumber flower and carries the seeds, like its relatives the melons and squashes. Cooks, and USDA's food groups, treat it as a vegetable.
Cucumber vs zucchini: how does the nutrition compare?
Both are mostly water and low in calories. Per 100 g raw, USDA's zucchini record has slightly more calories and nearly twice the protein of cucumber, but zucchini is usually cooked while cucumber is eaten raw.
What is a serving of cucumber?
This page defaults to 1/2 cup slices (52 g), a USDA household measure. The serving size on a packaged food label is set by the FDA reference amount (RACC) for its category, so a product label can use a different amount. The selector above shows every USDA measure for cucumber.
Can I use cucumber in a Nutrition Facts label calculation?
Yes. Open the generator with cucumber added, enter the weight you use, add your other ingredients and the label is calculated from the same USDA record shown here. A label for a product you sell must reflect your actual recipe and finished serving.

Source and method
Nutrient values are from USDA FoodData Central, SR Legacy (April 2018 release, public domain), record 168409: "Cucumber, with peel, raw". Values are stored per 100 g exactly as USDA reports them and scaled to each serving by weight. The Nutrition Facts panel applies the FDA rounding rules in 21 CFR 101.9; tables and text show the scaled amounts at reading precision, so a figure can differ slightly from the panel. A nutrient USDA does not report for this food is shown as not reported, never as a guessed value.
SR Legacy predates the added sugars field. This is a whole or unsweetened food, so added sugars are shown as 0 g. View the USDA record ↗
