How Much Does a Tree Frog Weigh? Species Compared
There is no single tree frog weight, because tree frogs are many species. Gray treefrogs average about 7 grams, red-eyed tree frogs weigh about 6 to 15 grams, and most adult White’s tree frogs weigh 50 to 90 grams. Females are usually larger than males, so weight also differs by sex.
Tree frogs range from the size of a paperclip to a small fist. Asking what a tree frog weighs is like asking what a bird weighs.
This page gives sourced weights for three well-known species and explains what changes a frog’s weight. For the group itself, read what a tree frog is.
How this was made: prepared with AI assistance and checked against the sources listed at the end. Images are AI-generated illustrations, not photographs of real animals or products.
Key Takeaways
- Weight varies by species: from about 7 g to 90 g in the examples below.
- Gray treefrogs average 7.175 g in one reference.
- Red-eyed tree frogs weigh about 6 to 15 g.
- White’s tree frogs usually weigh 50 to 90 g as adults.
- Females tend to be larger than males.

Tree frog weights by species
The table gives adult weights from two sources: the University of Michigan Animal Diversity Web and the Lafeber veterinary information sheet. We found weight data only for these three species in reputable sources, so we show only these.
| Species | Adult weight | Adult length | Source |
|---|---|---|---|
| Gray treefrog (Hyla versicolor and H. chrysoscelis) | Average 7.175 g | 3 to 5 cm | Animal Diversity Web |
| Red-eyed tree frog (Agalychnis callidryas) | About 6 to 15 g | 4 to 7 cm | Animal Diversity Web |
| White’s tree frog (Litoria caerulea) | Most adults 50 to 90 g | 5 to 11 cm | Lafeber |
Gray treefrog
Animal Diversity Web lists an average mass of 7.175 grams for gray treefrogs. It gives no mass range. Length ranges from 3 to 5 centimetres, and the record is 6 centimetres.
The page covers the eastern gray treefrog and Cope’s gray treefrog together and does not separate their measurements.
Red-eyed tree frog
Adult red-eyed tree frogs weigh about 6 to 15 grams and measure 4 to 7 centimetres, according to Animal Diversity Web. Females are the larger sex.
Weight within the range depends on the individual frog, its sex and its health, but the source does not break it down further.
White’s tree frog
Lafeber, a veterinary information site, says most adult White’s tree frogs weigh 50 to 90 grams. Length is 5 to 11 centimetres. The Zoological Society of London gives a maximum length of 11.5 centimetres.
The source does not break weight down further by age, health or sex.
Why sources differ
The Aquarium of the Pacific length range for White’s tree frogs is larger than the Lafeber range. Both are given as ranges, and they may measure differently or describe different populations.
Because sources disagree, treat any single number with caution. A range is more honest than a single figure.
What affects a frog’s weight
The sources show two clear factors. First, species: the heaviest example here is roughly ten times heavier than the lightest.
- Species and body size
- Sex: females are the larger sex in the red-eyed and White’s sources
- Age, health and feeding: our sources do not quantify these
A word on the older figure of 10 to 15 grams
Some pages give a single typical weight of 10 to 15 grams for tree frogs. That fits the red-eyed range well and is close to gray treefrogs, but it is far too low for White’s tree frogs.
Use a species name when asking about weight. A single figure for all tree frogs will mislead.
Frequently Asked Questions
How much does a tree frog weigh?
It depends on the species. Gray treefrogs average about 7 g, red-eyed tree frogs 6 to 15 g and White’s tree frogs 50 to 90 g.
How much does a gray treefrog weigh?
Animal Diversity Web lists an average of 7.175 grams.
How much does a red-eyed tree frog weigh?
About 6 to 15 grams, according to Animal Diversity Web.
How much does a White’s tree frog weigh?
Most adults weigh 50 to 90 grams, according to Lafeber.
Are female tree frogs heavier than males?
Females are the larger sex in the red-eyed and White’s tree frog sources. Lafeber says White’s males are 30 to 50 percent smaller.
Why do sources give different sizes?
Sources may measure differently or describe different populations. We show ranges and name each source.
Bottom Line
Tree frog weight spans about an order of magnitude, from a few grams to nearly 100. Always name the species before quoting a number.
