Raw Chicken Breast Weight by Type
A standard supermarket boneless skinless breast is 6-8 oz raw, but modern selectively-bred birds often produce much larger pieces.
| Type | Weight (oz) | Weight (g) |
|---|---|---|
| Small boneless skinless | 4-5 oz | 115-140g |
| Average boneless skinless | 6-8 oz | 170-225g |
| Large boneless skinless | 10-12 oz | 280-340g |
| Bone-in skin-on | 12-14 oz | 340-400g |
| Chicken tender (1 piece) | 1-1.5 oz | 28-43g |
How Cooking Changes the Weight
Chicken loses moisture during cooking. The amount depends on method. Grilling and baking lose the most, sous vide the least.
| Method | Weight loss | Cooked weight |
|---|---|---|
| Grilled at 425°F | 25-30% | ~5 oz / 140-150g |
| Baked at 375°F | 20-25% | ~5.3 oz / 150-160g |
| Pan-seared | 15-20% | ~5.7 oz / 160-170g |
| Poached / sous vide | 10-15% | ~6 oz / 170-180g |
Calories: Raw vs Cooked
Raw chicken breast is 120 cal per 100g (34 cal/oz). Cooked is 165 cal per 100g (47 cal/oz) because water left but calories stayed. A 7 oz (200g) raw breast = 240 cal whether you weigh it raw or after cooking. Stay consistent and use raw numbers with raw weight, cooked numbers with cooked weight.
Estimating Without a Scale
A breast the size of your palm (no fingers) is about 4-5 oz (115-140g). The size of a deck of cards is 3-3.5 oz (85-100g). The size of your full hand is 7-9 oz (200-250g). For an exact estimate, snap a photo with our AI scale tool.
Tips for Consistent Portions
Buy a family pack and pre-weigh portions before cooking. Butterfly oversized breasts horizontally to create even 5-6 oz (140-170g) pieces that cook through without drying. Pre-portioned breasts at the supermarket are usually trimmed to about 6 oz (170g) each.
Frequently Asked Questions
How much does an average chicken breast weigh?+
A boneless skinless chicken breast weighs 6-8 oz (170-225g) on average raw, or about 5 oz (140g) cooked after grilling.
How much does a chicken breast weigh in grams cooked?+
A 7 oz (200g) raw breast weighs about 140-150g (5 oz) after grilling, 150-160g after baking, or 170-180g after sous vide.
How many calories in 8 oz of chicken breast?+
8 oz (225g) of raw boneless skinless chicken breast has about 270 calories and 53g of protein. The same chicken cooked is the same calories but weighs less.
Why are chicken breasts so big now?+
Modern broilers are selectively bred to grow faster and yield 30-40% more breast meat than chickens from the 1950s. A typical commercial breast today weighs nearly twice what it did 50 years ago.
Should I weigh chicken raw or cooked for calorie counting?+
Both work as long as you stay consistent. Raw weight with raw nutrition data (120 cal/100g), or cooked weight with cooked data (165 cal/100g). Mixing the two throws calories off by ~25%.
How much does a bone-in chicken breast weigh?+
A bone-in skin-on chicken breast weighs 12-14 oz (340-400g). The bone is about 20% and skin about 10% of total weight, so about 8-10 oz (225-280g) is edible meat.
