Meeting Centre of Gravity for UK Postcodes

Use this tool to find the best place to hold a meeting for it's attendees by inputting their UK postcodes. The COG tool will then work out the centre of gravity for the meeting. This will be represented by a marker on the map.

Further Information

Once you input the postcodes, this tool will work out where the best place is to hold the meeting. This will be a point on the map where, if all attendees could travel in a straight line to get to, would give the least combined travel time for them to meet up. You can enter full UK postcodes (incode & outcode) for more accuracy.

Yes, of course people cant travel in straight lines and they cant hold the meeting in a field, in the sea or in some strangers house if that is what the tools tells you. You are then expected to use that as a base from which to find a meeting venue close by, be it a pub, park or hotel etc..

Let us know if this tool comes in useful to you by posting a comment below. It will be interesting to find out how it is used.

This is good for what it is, but how can I find the \"centre of minimum distance\"? So the total distance to travel is minimised, not just individual journeys.

Need to input a full postcode...

Just enteted 4 UK postcodes (just the first part e.g CF72) - doesn't work. Just keeps saying 'loading'.....

Can you try loading the page again and see if it works? When you say "won't accept my own postcode", what is your postcode?
By Free Map Tools on 15th March 2019

Just keeps loading and won't accept my own postcode. Removing it didn't help.

I had a calculation of 6 addresses and worked brilliantly. One person dropped out and I removed an address. The calculation kept the original address in.

Thanks for clarification <3

Jacob, this page is for UK postcodes. On reflection there is no clear indication of that on the page, sorry. Thank you for not just saying "It doesn't work" and taking the time to explain in reasonable detail. The page will be updated to put "UK" in the text.

It doesn't seem to work for me, it just keeps loading perpetually. I tried entering the postcodes with and without the hyphen. For the record, these are Polish postcodes. Also, the same happens on other browsers. Let me know if you come up with any solutions.
By Jacob on 19th February 2019

Yes it does

Does this only work for the UK?

Excellent - needed to find a central point for several families from the north, west, east and south to meet up. Still got to decide on a venue but at least we know where to look.

Really useful for organising a work meeting with people from all over the north west and north east

I have just found this after spending a while trying to guess a rough centre point for a meet up with friends who live in completely different directions from each other! It's really useful, thank you very much for creating this site.

Just found this site and the tools it provides. Great work by all concerned. Thank You!

Hi. Very pleased to discover this tool. I am wondering if it could offer a simplified output based on nearest railway station? And possibly a few more delegates? But thanks for missing Big Brother - this is a much better use of time!!
By Simon at LI on 23rd January 2017

Stu, thanks for the suggestion. This is being considered. I think you have a good idea.
By Free Map Tools on 14th June 2016

Firstly, this is very helpful thank you! Please can we have option to export postcodes and add names next to them to save for future import on iOS device e.g. Dropbox import file that you've exported? Ideally would like this in your app to add contacts and save them, for planning trips where we can all meet. Thank you!
