This budgie weight calculator checks whether your budgie is a healthy weight, underweight or overweight from its weight in grams and type, backs it up with a keel-bone body check, and shows the healthy weight ranges. A standard budgie is usually 30 to 40 grams; English show budgies are larger.
A standard budgie is healthy at about 30–40 g (English show budgies 45–60 g). Weight alone can mislead, so feel the keel bone too, and treat a change of about 10% in a week as a vet visit.

How the Budgie Weight Calculator Works
The budgie weight calculator compares your bird’s weight in grams against the healthy range for its type. A standard (pet) budgie is healthiest at about 30 to 40 grams — roughly 28 to 46 g across individuals — while a larger English (show) budgie is normal at about 45 to 60 grams. Below the range is underweight; well above it (around 50 g+ for standard budgies, 65 g+ for English) is overweight. Because body frames differ, the number is only half the picture, so this tool pairs it with a keel-bone body-condition check you can do by hand.

Weigh your budgie on a digital gram scale at the same time each morning — after it poops, before it eats — and track the trend. A sudden change of about 10% within a week or two is a warning sign that warrants an avian vet.
Healthy Budgie Weight Ranges
This chart shows where standard and English budgies sit on the scale, with the healthy bands highlighted. Notice how much heavier English show budgies are — a 55 g English budgie can be perfectly healthy while the same weight would be obese on a small standard bird.
How Much Should a Budgie Weigh?
A healthy standard budgie weighs about 30 to 40 grams, with individuals ranging from roughly 25 to 45 g depending on frame size. English or show budgies are a bigger bird and normally weigh 45 to 65 grams, sometimes more, so they are not overweight simply for being heavier than a pet budgie. There is no single “correct” number: a small-framed bird can be ideal at 30 g while a large-framed one is ideal at 42 g. That is why vets look at the trend over time and the body condition rather than a one-off reading, and why you should learn your own budgie’s normal baseline by weighing it regularly.
How to Tell if a Budgie Is Overweight
The best check is the keel bone — the breastbone running down the centre of the chest. Gently feel it with clean, bare fingers: in an ideal bird the keel is easy to feel as a slight ridge and the breast muscles on either side are rounded and even. In an overweight bird you struggle to feel the keel because it is buried under thick muscle and fat, often with visible fat pads on the chest and lower belly. In an underweight bird the keel sticks out sharply like a knife edge and the muscle feels sunken. On the scale, a standard budgie creeping past about 48–50 g (or an English budgie past the mid-60s) is a flag to review diet and exercise — usually by cutting seed and millet, adding vegetables, and giving more out-of-cage flight — but never crash-diet a bird; slim it gradually under an avian vet’s guidance.
How to Weigh a Budgie
Use a digital kitchen or jewellery scale that reads in grams, ideally to a tenth of a gram. Rest a light T-perch, a small bowl or a flat lid on the scale and tare (zero) it, then encourage your budgie to step on — a dab of millet can help it hold still. Weigh at the same time each day, usually first thing in the morning after the bird has pooped and before it eats, so readings are comparable. Note the number and watch the trend: day-to-day wobble of up to about 5% (a gram or two) is normal, but a steady fall, a steady climb, or a sudden 10% change means a call to an avian vet. Regular weighing is one of the simplest ways to catch illness early, because birds instinctively hide being unwell.
Frequently Asked Questions
How many grams should a budgie be?
A standard pet budgie is healthy at about 30 to 40 grams, with a wider individual range of roughly 25 to 45 g. English or show budgies are larger and normally weigh 45 to 65 grams. Frame size matters, so pair the number with a keel-bone body check rather than treating one weight as the only correct figure.
Is my budgie overweight at 45 grams?
It depends on the type. For a small standard budgie, 45 g is at the upper edge and may mean it is a little heavy, so check the keel bone. For an English or show budgie, 45 g is squarely within the normal range and not overweight at all. The breastbone feel and the trend over time tell you more than the single number.
How do I check my budgie’s weight without a bird scale?
Any digital kitchen scale that reads grams works. Put a light perch or small bowl on it, tare it to zero, and coax the bird on with a little millet. If you cannot weigh at all, feel the keel bone: a slight ridge with rounded muscle is ideal, a sharp prominent keel is underweight, and a keel you cannot find under fat is overweight.
How much can a healthy budgie’s weight change day to day?
Up to about 5%, a gram or two, is normal and reflects food, droppings and the time of day you weigh. A swing of 5 to 10% is worth watching over a few days, and a change of more than about 10% from the bird’s baseline within a week or two is a warning sign that calls for an avian vet, since birds hide illness well.
Do male and female budgies weigh different amounts?
Not by much. In standard budgies males and females sit in the same 30 to 40 gram range, and sex is not a reliable way to predict weight. Type and frame size matter far more: an English show budgie of either sex weighs more than a standard pet budgie. A hen may gain temporarily when in breeding condition or carrying an egg.
What should a baby budgie weigh?
A budgie chick grows very fast, from about 1 to 2 grams at hatch to roughly 28 to 34 g by four weeks and near its adult weight of 30 to 40 g by fledging at about five weeks. Hand-feeders should see steady daily gains, and any weight loss in a growing chick is urgent, so contact an avian vet or experienced breeder straight away.
This budgie weight calculator uses widely published healthy ranges — about 30–40 g for standard budgies and 45–60 g for English/show budgies — alongside the standard keel-bone body-condition method. Figures are general guidance, not veterinary advice, and healthy weight varies with frame size, type and breeding state. Birds hide illness and must not be crash-dieted, so weigh yours regularly, learn its baseline, and see an avian vet for any sudden change of roughly 10% or signs of illness.
