Answer-first summary
A small ear of corn (about 100 grams kernels) typically provides roughly 20–25 grams of total carbohydrates, though the exact amount varies by variety, growing conditions, and measurement method. This overview explains what “small” means in weight and servings, how carbs are measured, and how variables such as hybrid, harvest stage, and preparation method influence the final number. Use this as a practical reference for meal planning, carb tracking, and comparing fresh versus prepared forms.
What we mean by a small ear of corn
In everyday usage, a small ear of corn often refers to a single ear that fits comfortably in one hand, generally weighing around 100–120 grams in the kernel portion. Market sizes can vary, and the weight may shift slightly depending on moisture and ear thickness. For nutrition purposes, professionals and labels typically refer to standardized reference portions rather than a single physical ear, so translating “small ear” into grams or servings is essential for accurate carb counting.
Typical weight and yield notes
- Kernel weight (approximate): 100–120 grams for a small ear
- Whole ear with husk: 120–160 grams, depending on size and moisture
- Kernels after removal and trimming: close to the kernel weight listed above
Carbohydrate content and measurement basics
Total carbohydrates include starch, natural sugar, and dietary fiber. Values are commonly expressed in grams per serving or per 100 grams of edible portion. For a small ear measured as about 100 grams of kernels, expect approximately 20–25 grams of total carbohydrate, with the majority as starch and a smaller amount as naturally occurring sugar and fiber. Preparation state (raw, boiled, grilled) can slightly affect water content and perceived density but does not typically change the total carbohydrate mass in a typical serving.
Variables that influence carb levels
- Hybrid and cultivar: starch and sugar profiles differ
- Harvest maturity: more mature kernels may have higher starch
- Moisture and preparation: raw versus cooked changes weight but not total carbs in the portion
- Serving precision: whether the cob is included or excluded
Verified ranges and reference data
Published nutrition databases and agricultural sources provide a basis for estimating carbohydrate content. The table below summarizes commonly reported values for a small ear portion (approximate 100 grams edible kernels).
| Attribute | Verified Detail / Estimate | Source Type |
|---|---|---|
| Portion weight (approximate) | 100 grams kernels | USDA FoodData Central reference weight |
| Total carbohydrate | 19–22 grams | USDA and comparable databases |
| Dietary fiber | 2–3 grams | USDA and peer-reviewed composition tables |
| Sugars | 3–5 grams | USDA and crop analysis reports |
| Starch (majority) | 12–16 grams | USDA and crop nutrient summaries |
Practical notes for carb tracking
When you count carbs for meals or blood-sugar management, treat a small ear of corn as roughly one starch serving, similar to a small portion of cooked cereal or grain. If you eat the cob or add butter and salt, those add fats and sodium but do not materially change carbohydrate totals. For prepared forms such as creamed corn or corn chowder, account for added milk, sugar, or thickeners, as they increase total carbohydrate and calories beyond the base kernel value.
Quick comparisons (approximate)
- Small ear (≈100 g kernels): 20–25 g total carbohydrate
- 1 slice of bread: ~12–15 g carbohydrate
- 1/2 cup cooked rice: ~22–24 g carbohydrate
- 1 medium apple: ~25 g carbohydrate
Bottom line
A small ear of corn—about 100 grams of kernels—provides approximately 20–25 grams of total carbohydrate, the majority as starch, with some natural sugar and fiber. This is a useful, evergreen reference for understanding carb content, comparing portion sizes, and integrating corn into balanced meal plans or carbohydrate tracking routines.
FAQ
Reader questions
Does cooking change the carb count in corn?
Cooking primarily changes water content and texture; the total carbohydrate in a given weight of kernels remains similar. Boiling may cause some starch to leach into water if you discard the cooking liquid, slightly reducing carbs in the kernels if you eat them alone.
What if I eat the entire ear with cob and husk remnants?
Inclusions of cob or very fibrous husk material add minimal digestible carbohydrate but can increase fiber-like fractions. For practical carb tracking, use the kernel weight estimate and note that whole-ear numbers may be slightly higher.
How do canned or frozen small ears compare?
Canned and frozen kernels from a small ear typically match the carbohydrate range above, though canned versions may contain added salt or light syrup, which can affect sodium and total carbohydrate slightly. Always check labels for specific nutrition facts.
Are sweet corn varieties different in carb content?
Sweet corn may have a bit more sugar and slightly less starch than standard starchy field corn, but the total carbohydrate per small ear remains in a similar range. Label data or specific lab analyses are the best sources for distinct varieties.
