What Is The Average Size Of Budgies?

The size of budgies, like many creatures, can vary greatly depending on a variety of factors.

Type of BudgieAverage Size (cm)Average Size (inches)
Wild Budgie18 cm7 inches
American Budgie18-20 cm7-7.8 inches
English Budgie22-24 cm8.6-9.4 inches

Let’s explore some of these variations, starting with budgies in their natural habitat.

Wild Budgie Size

When you cast your mind to the expansive landscapes of the Australian outback, you’ll find the birthplace of the wild budgies.

These original budgie variants are noticeably smaller than their domesticated counterparts, averaging about 18 cm (7 inches) in length from the beak’s tip to the tail feathers’ end.

This petite size serves them well, providing agility and speed necessary for survival in the wild.

It’s fascinating how their size has been naturally adapted for a life filled with constant movement and alertness, typical of their wild environment.

English Budgie Size

As we journey from the wild Australian outback into the realm of selective breeding, we encounter the English Budgie.

This breed stands out for its distinctive size, significantly larger than its wild and American counterparts.

On average, English Budgies measure between 22-24 cm (8.6-9.4 inches) in length.

Their increased size is a result of years of selective breeding with the intention of creating a budgie that not only serves as a companion but also holds its own in bird shows, adding an interesting dimension to the world of budgies.

Why Are English Budgies Larger Than Other Budgies?

The story of the English Budgie’s larger size begins with a unique journey of selective breeding.

To stand out in bird shows and catch the eye of discerning judges, breeders cultivated the English Budgie to be more prominent and more robust than their wild counterparts.

The breeders’ primary objective was to create a bird that would make a striking statement and thus, through careful and selective breeding over the years, the English Budgie grew in size.

Selective breeding allowed for the passing of desired traits from one generation to the next.

As breeders continuously picked the larger budgies for breeding, these size traits became more pronounced over generations, leading to a distinctively larger breed.

This process took years of careful selection and breeding, ensuring that the desired traits were maintained.

However, it’s important to remember that the larger size is not just an aesthetic choice.

English Budgies are often more docile and less active than their smaller counterparts.

Their larger size means they do not need to expend as much energy to survive, unlike their wild relatives who need to be agile to escape predators and find food.

Therefore, the size of English Budgies is a blend of human intervention and adaptation to a life of domesticity.

American Budgie Size

The American Budgie, also widely known as the parakeet, is a charming variety that is closer in size to the wild Budgie.

Their size ranges from 18-20 cm (7-7.8 inches) in length, making them slightly larger than the wild budgies but still smaller than the English variety.

The American Budgie’s size allows them to retain the agility of their wild counterparts while being suitable for domestic life, thus creating a perfect blend of nature and nurture.

Male Budgie Size

Male budgies, like their female counterparts, measure approximately 18-24 cm (7-9.4 inches) depending on the breed.

However, it is important to note that size alone is not a reliable indicator of a budgie’s gender.

Female Budgie Size

Similar to males, female budgies range in size from 18-24 cm (7-9.4 inches).

While size differences between male and female budgies are minimal, females can often have a slightly more robust build.

What Are The Factors Affecting The Size Of The Budgerigar?

Genetic Factors

In the world of budgies, genetics play a crucial role in determining their size.

Just as humans inherit traits like height and eye color from their parents, budgies also inherit size traits from their lineage.

Genes, passed down from generation to generation, dictate the potential size a budgie can reach.

This is why English Budgies, which have been selectively bred for their larger size, are often bigger than their American or wild counterparts.

Genetics provide the blueprint for growth, and it is within these complex structures of DNA that the size of a budgie is largely determined.

Living, Environmental Factors

Environmental factors, along with genetic makeup, shape the size of a budgie.

The conditions under which a budgie is raised, including its habitat and the availability of resources, can influence its growth.

A stress-free environment that mimics their natural habitat encourages healthy development.

Adequate space for flying and exercising, for instance, helps budgies develop strong muscles and maintain a healthy weight.

Similarly, exposure to natural sunlight or an appropriate substitute is important for their overall well-being.

Thus, the environment can be a significant determinant in how big a budgie gets.


A budgie’s age can affect its size, with younger budgies being smaller.

As the budgie grows and matures, it will reach its full size.

Diet, Nutrition

The role of diet and nutrition in a budgie’s size cannot be overstated.

Just as humans need a balanced diet to grow and develop, so do budgies.

A diet rich in essential vitamins, minerals, and the right balance of proteins, fats, and carbohydrates contributes to healthy growth.

A variety of seeds, fresh fruits, and vegetables supplemented with appropriate bird-safe grains and legumes forms an ideal diet.

Malnutrition, on the other hand, can stunt growth and lead to smaller, underdeveloped budgies.

Hence, providing a diverse and nutritionally balanced diet is key to ensuring budgies reach their optimal size.

Health And Wellness

The overall health and wellness of a budgie greatly impacts its size.

Budgies that are healthy and free from illness generally grow to their full potential size.

Conversely, health issues, especially those affecting a budgie during its growth phase, can result in a smaller size.

Diseases affecting the digestive system, for instance, can hinder nutrient absorption leading to malnutrition and stunted growth.

Similarly, chronic stress or living in unsuitable conditions can impact a budgie’s overall health and consequently its size.

Therefore, regular veterinary check-ups, appropriate care, and prompt treatment of any health issues are crucial for a budgie’s growth and development.


In some bird species, including budgerigars, there may be slight differences in size between males and females.

However, in budgies, the size difference is minimal and not a reliable indicator of gender.


Do Budgies Get Bigger Or Smaller As They Get Older?

Budgies grow as they age, with the most significant growth occurring during their first year.

After this, their size remains relatively stable.

At What Age Is A Budgie Fully Grown?

Most budgies are considered fully grown by the time they reach one year of age.

What Is The Biggest Budgie Breed?

The biggest budgie breed is the English budgie, which was developed through selective breeding to be larger and more robust.

Why Is My Budgie So Large Than Other Budgies?

If your budgie is larger than others, it could be due to several factors.

These could include its breed (maybe it is an English budgie.), diet, or overall health status.

How Can I Ensure My Budgie Reaches Its Full Size Potential?

To ensure your budgie reaches its full size potential, provide it with a healthy, balanced diet, an enriched environment, and regular veterinary check-ups.

What Is The Average Weight Of A Budgie?

The average weight of a budgie ranges between 30-40 grams, although this can vary depending on the breed and overall health of the bird.

What Is The Typical Wingspan Of A Budgie?

The typical wingspan of a budgie can range between 10 to 14 inches.

However, like their body size, this can be influenced by factors such as breed, diet, and overall health.

Are There Significant Differences In Size Among Different Colors Of Budgies?

No, the color of a budgie does not influence its size.

Whether it’s a vibrant green, a deep blue, or an albino, a budgie’s size is largely determined by its breed and genetic factors, rather than its color.

How Does The Size Of A Budgie In Captivity Compare To Those In The Wild?

Budgies in captivity, especially English Budgies, tend to be larger than their wild counterparts.

This is largely due to selective breeding and access to abundant and consistent food sources in captivity.

Do The Sizes Of Budgies Vary Across Different Geographic Locations?

The size of budgies can vary slightly based on geographic locations, primarily due to variations in environmental factors and genetic influences.

However, the most significant difference in size is seen between the different breeds, such as English and American budgies.

Can The Size Of A Budgie Indicate Its Lifespan?

While larger bird species generally have longer lifespans, within the budgie species, size does not directly correlate with lifespan.

A budgie’s lifespan is more closely tied to factors like diet, health, and care rather than size.
