2Download the building instructions from LEGO

The bags are only shown in the official building instructions. Download the PDF from LEGO to your own device. If your set has several booklets, download them all.

Enter the set number above first; the link to the right page at LEGO will then appear here.

3Choose the PDF files

Select all booklets of the set at once. Processing usually takes half a minute to a minute.

Your files stay on your own device. They are processed in your browser and not sent to us.

How does it work?

The building instructions show which parts you need for every step, and a large number at the start of every bag. The generator reads that from the file and adds up all parts per bag.

Everything happens in your own browser. We never see the booklet and store nothing.

Good to know

  • It works for sets with numbered bags, which covers most sets of recent years. Small and older sets often do not have them.
  • Minifigure parts are shown without a quantity in the instructions. We mention them but do not count them.
  • Below the result you find a check: the counted number next to the official part count of the set.
  • For the occasional booklet recognition can fail. We then say so; you will not get half a list.
