🧰 Tackle Box Weight Calculator

Add each item in your tackle box with its weight to see the total — handy for travel weight limits or balancing a kayak or boat.

What the total is doing

Every row you fill in is added in ounces, then divided by 16 for the pounds figure on the card:

total oz  = sum of every item weight
total lbs = total oz ÷ 16

The three rows the page starts with — a 24 oz empty box, 8 oz of lures and an 8 oz reel — come to 40 oz, which is 2.50 lbs. Add Item drops in a new 4 oz line you can rename, Remove takes one out, and the total updates as you type. Ounces are shown to one decimal, pounds to two.

Weighing and converting

Ounces only. There is no metric input, so divide grams by 28.35 before typing — a 250 g reel is 8.8 oz, and 1 kg is 35.3 oz.
Weigh the box empty first. A kitchen scale and one row per tray is more accurate than guessing at a full box, and it shows you which tray is worth leaving at home.
Group sensibly. One row for "soft plastics" beats forty rows of single packets; the arithmetic is the same and the list stays readable.

Two places this total earns its keep. Checked baggage is commonly capped at 50 lbs, so a box near that is worth splitting before you reach the desk. And a kayak's stated capacity covers you, your gear and any water aboard, not the gear alone — loading well under the sticker is the usual advice.

Frequently asked questions

How many ounces are in a pound?

Sixteen. That is the only conversion this page does: the 40 oz default reads back as 2.50 lbs, and a 10 lb box would be 160 oz.

How do I enter a weight given in grams?

Divide by 28.35. A 250 g reel is 8.8 oz, a 500 g box is 17.6 oz. Doing it the other way, an ounce is 28.35 g, so the 40 oz starting total is about 1,134 g.

Why weigh a tackle box at all?

Because weight limits are real ones. Airlines charge for overweight bags, small boats and kayaks have a capacity rating that your body weight already eats into, and anything you carry to a bank swim you carry back again.
