I am building an inventory of all my Lego pieces and I am looking for a website that can give the pieces in a set with only the set number. It would be easier if there was information for many Lego sets with the full inventory. I also will need to have a file of all Lego parts.

I have found a file that may help. Here it is. I haven't looked at it yet. I'll add it as an answer if it is right. – Hello World Jul 20 '13 at 2:35
Peeron sounds just like what you're looking for. You can add sets to your account, and view how many of a certain piece you own, and in what colours. – shea Jul 20 '13 at 3:10
Peeron USED to be awesome. Then, one day, I came home with some new sets and Peeron HAD NO CLUE. That was about three years ago, and the only sets I've added since then are the architecture sets, since they were seriously easy to remember. So, currently I'm adrift in the inventory department. frump – gev Jul 20 '13 at 5:41

Here are the options that I'm aware of along with some basic pros and cons:


This site is great for old sets, and has some nice functionality including the ability to compile a list of all the parts in all of your sets for you have. This makes it easy to start your part inventory. All you have to do is import your sets and then export your parts list.

Bricklink Inventory Reference

Unlike Peeron, Bricklink is getting updated constantly, so it shouldn't have issues with newer sets. These inventories are also very detailed and include extra parts, sticker sheets, etc. If you are a seller on Bricklink, you can also part out sets into your inventory which could be useful to you at some point.

Brickset /

TLG provides nearly complete inventories for sets online via the replacement parts page. You can use this to get part information from your sets, but the interface is lacking because this isn't really what the page is meant for.

Brickset provides this same part data in a format which is much better for viewing. Simply search for a set and use the "Parts" tab to view contents if they are available.

These resources have a couple of downsides:

  1. They only include relatively new sets.
  2. Set inventories aren't as complete as Peeron or Bricklink.


Rebrickable also provides set inventories. Once you search for a set, you can scroll down to find a list of parts. This source includes sets from all time, and is still being updated as new sets come out. Rebrickable also provides set inventories for offline use via its download page.

Very comprehensive answer, +1 – shea Jul 24 '13 at 21:36
I use Rebrickable and have found the site-owner to be very friendly and open to feedback. As you point out, the philosophy is to help build sets, not to catalog each variation of a piece. For that reason, the site originally did not distinguish between some colors such as the "old" and "bley" tones of gray. I see the site now does distinguish between them, but unfortunately for me I had entered the bulk of my collection before that. – 62Bricks Jul 27 '13 at 13:22

Try the bricklink catolog. They also have inventories like Peeron, but a little bit more detailed (like part variations) and also include stuff like extra parts and Ninjago cards.
