How Do I Weigh My Package?
Accurate shipping starts with an accurate weight. Here’s how to weigh your package the right way — so you get the correct rate and avoid surprise USPS adjustments later.
- Use a digital scale on a flat surface, with the package fully packed and sealed.
- Weigh everything together — item plus all packaging.
- On Thryft Ship you can enter the weight in ounces — we do the pounds math for you.
Step by step
-
Grab a digital scale
A postal scale is ideal, but a kitchen scale works fine when you’re starting out — affordable options run under $10. Set it on a stable, flat surface.
-
Zero it out
Turn the scale on and make sure it reads 0 before you place anything on it. If it measures in ounces, that’s perfect for Thryft Ship.
-
Weigh the whole package
Place your fully packed and sealed package in the center of the scale, with nothing hanging over the edge. Weigh it once or twice to confirm a consistent reading.
-
Enter the weight on Thryft Ship
Type the weight straight in — ounces are fine, we’ll convert to pounds automatically (there are 16 ounces in a pound).
Common questions
Do I need a special postal scale?
No. Any digital scale that reads in ounces works. A kitchen scale is a fine starting point — just make sure it’s accurate and zeroed.
Do I weigh the item with or without packaging?
With. Weigh the fully packed, sealed package — USPS charges based on the total shipped weight, packaging included.
What if my scale only shows ounces?
That’s fine — enter ounces directly on Thryft Ship and we’ll handle the pounds conversion for you.
Once you’ve got an accurate weight, you’re ready to buy your first label. Need to set up packaging defaults? See Default and Custom Package Types.
