Many people remain confused over the weight of the chicken breast. Knowing the weight is important to measure the intake of nutrients for cooking purposes. Actually, the measurement of chicken breast is influenced by a lot of variables. 

On an average scale, uncooked chicken breast weight ranges from 4-8 oz, whereas cooked chicken breast ranges from 2-5 oz. Weight can also vary depending upon the type of chicken, boneless, bone-in, skinless, or skin-on chicken breast. But the most used breast is boneless and skinless and weighs 6-8 oz.

All of these variables can be a tad bit confusing. Don’t worry, I will explain each and every detail in-depth you need to know about the chicken breast below. So, let’s get started. 

Average Weight of a Chicken Breast

In today’s era, the average weight of chicken breast has increased a lot compared to 30-40 years ago. The main reason behind this is the advancement in technology and healthcare. If you ask your grandfather or grandmother, they would probably give you an idea about the size of chickens in their time. 

In my opinion, the weight of chicken breast depends upon mainly 2 factors:

  • Is it boneless, bone-in, skinless, or skin-on?
  • Is it mass-produced, supermarket chicken, local or homegrown?

The above two are the main variables that will determine the size and weight of the breast. 

Type of Chicken BreastWeight (in ounces)Weight (in grams)Weight (in pounds)
Boneless (Skinless)6-10 oz170-283 g0.3-0.6 lb
Boneless (Skin-On)7-12 oz198-340 g0.4-0.7 lb
Bone-In (Skinless)10-15 oz283-425 g0.6-0.9 lb
Bone-In (Skin-On)11-16 oz311-453 g0.6-1 lb

When a chicken breast is cooked, it loses nearly 3-4 ounces. Now, you must have an idea about the weight of the chicken breast. But, if you buy breast from the grocery or supermarket, then you will get nearly 3-4 boneless breasts per pack. So, each packing can have a different weight as each breast has a different weight. 

To calculate the weight of the pack, just add the total weight and divide by the number of chicken breasts.

For example, if the weight of a pack is 36 oz and there are 4 chicken breasts in the pack, then divide 36 oz by 4. That means the weight of each breast is 9 oz.

One reason that supermarket chicken will weigh more than the mass-produced, local or homegrown chicken is that the chicken farms make use of special techniques to make the chickens bigger. According to some reports, some chicken farms use hormones and antibiotics to increase the overall size of the chicken. 

Most restaurants in the USA use chicken breasts ranging from 6-8 oz. The recommended serving is 4-6 oz or smaller than the human hands. If it is bigger than the hands, then it can be considered that the breast is bigger than the normal average size.

Average Weight of Chicken Breast in Grams 

To know the average weight of the chicken breast in grams, just convert ounces to grams. 1 ounce = 28 grams.

Weight of An Average Chicken Breast in lbs

To know the average weight of the chicken breast in grams, just convert ounces to pounds. 1 ounce = 0.06 pound.

A few years back, there were 10-12 breasts in the pack, but they weighed less and now, their number has decreased to 4-5, but they weigh the same as 10-12. As there is a rise in broiler chicken, the farms focus more on making the chickens big and healthy.

Chicken breast is actually the chicken’s pectoral muscle and is found on each side of the chicken chest. They are then separated and known as chicken breast halves or chicken breasts. 

There are some reports according to which big farms use hormones and water to make the chickens appear big. If you buy chicken from a butcher, then it may be less in weight than the ones sold in supermarkets.
