The average bell pepper weighs approximately 0.25 to 1 pound, including the stem and seed core. Actual bell pepper weights vary depending on variety, with some cultivars producing thicker walls. Growth factors, such as plant spacing, soil conditions, watering frequency and access to sunlight, also affect weight.
Block-shaped peppers typically measure 4 to 6 inches in width and height, while long varieties grow up to 8 inches long. One large bell pepper equals 1 cup chopped or 1 1/4 cups sliced. Bell peppers, also called sweet peppers, are grown in a variety of colors, including green, red, yellow, orange, purple and white. One bell pepper contains approximately 30 to 46 calories, 7 to 9 grams of carbohydrates and less than 1 gram of fat.
