Two things decide a tripod: what it can hold and how tall it stands. Add up the body, the lens and accessories such as a flash, enter the safety factor you want to work with, and the load capacity you need comes back. Enter your height, your crown-to-eye distance and the ball head height and you also get how far the legs have to extend to reach eye level.
Load capacity needed is the total load on top multiplied by the safety factor. Eye-level height is your height minus the crown-to-eye distance, and the leg height needed takes the ball head off that. No official standard for the safety factor exists, because makers measure load capacity under their own conditions. That is why the factor is an input rather than a constant and is printed back with the results. Current as of October 2026.
The figures assume legs fully extended with the center column down. Wind, shutter vibration and the twist that comes with thinner legs are not reduced to numbers. Recommending a particular model, minimum low-angle height and folded length are not covered. Treat the results as a reference and check the measurement conditions in the product data.
Frequently Asked Questions
No official standard exists. Makers measure load capacity under different conditions, so the same number does not mean the same thing twice. Read the conditions in the data for the model you are eyeing and enter whatever margin you are willing to accept.
Stand at a mirror and measure from the top of your head to the center of your pupil. It varies from person to person, so it is an input rather than a constant. If you are unsure, try figures around 4 in.
No. The tool only multiplies the load on top by your safety factor and subtracts the ball head from your eye level. Checking the measurement conditions in the product data is up to you.
