Weight estimation is as easy as taking 3 measurements and entering it into the calculator below. Your estimate gives you an idea of what to expect when you get to your weigh-off. It has been calculated from data collected over the years with clever mathematics applied.
The three measurements you need are:
1. Circumference – Measure the circumference of the fruit parallel to the ground at stem height.
2. End to end – Place your tape measure on the ground at the stem end, and at the blossom end. Measure the distance from ground to ground.
3. Side to Side – Placing the tape perpendicular to the plant stem at the widest point of the pumpkin. Place it on the ground on both sides, and measure this distance.
If you don’t have a flexible measuring tape, use a piece of string and hold this up to a regular tape measure to get the length.
Weight Estimation – How To
- Take the three measurements outlined above.
- Use the calculator below and enter all 3 figures you have measured into the giant pumpkin weight estimation calculator (make sure to pick the right measurement first)
- Or add them together to get a total figure and use the charts at the bottom (calculator is better 😄)

Note: There are both metric and imperial charts, I’ve included both. I’m using the 2025 estimation charts.
All of them are in PDF, click the buttons below each chart to enlarge them if needed.

- These measurements are only for the Atlantic Giant variety.
- This giant pumpkin estimation chart is intended as a rough guide only, with many variables including soil, pumpkin growth, fertiliser etc it is hard to have totally accurate data.
- The giant pumpkin weight estimation calculator is provided as is.
- This is the best method for estimating a pumpkin’s weight, but will not replace actually weighing your pumpkin on a proper set of calibrated scales.
your metric weighing scale makes life a bit easier but does it weigh light going by guesstimation of last years weigh in in oz I think my fruit should be 40,50 kg,s heavier would that be right
Hi Dave, thanks for the comment. The weight table always comes up all the time in conversation. It is only a tool for estimation, it is from older US data, as we don’t have the data for us to make our own table yet.
In saying that, I found it to guess too heavy over here, with the pumpkins being a bit lighter then what the chart said.
Hopefully it is lighter in your case, and you end up with a heavier pumpkin, let me know how you go. If I get a more accurate chart, or method I will put that up.
love the calculator. thanks for making this available.
Thanks Chad, glad you like it and have been using it 😀
From a fun pov the estimator if used for everyones pumpkin gives a good ball park figure. But every pumpkin must be weighed using this method to make it fair. I found it to be about right but my punkys are still mini giants compared to the weights mentioned below!
The only real indicator of weight is to use proper scales. But the weight estimation calculator is a great tool to get an estimate. It’s also great in helping track a pumpkins growth with consistent use.
Thank you for posting this. First year grower and I have been using it every day for the past 32 days!
Thanks for using it 😀
