Trying to figure out a way to make a grid in Excel that will print out in with spacing of mm's. Haven't figured out a way to do this yet though.

I'm doing some work with Nanoblocks (which a single 1x1 is 4mm x 4mm), and I want to have a grid to work with, I might even layout the design in Excel (just filling cells), but this later part will be manual, just really need the correctly sized grid (printed).

    Keep in mind the printer itself is going to have a lot to do with the precision of the grid printed. – CharlieRB Apr 1 '14 at 15:27

    As it turns out, Excel does some rounding, which keeps it from having a precise mm size... (Another thing for anyone else, which I did ensure, is to make sure that your printer settings are set to NOT scale the page to fit) – BondUniverse Apr 1 '14 at 18:17

To change the default measurement to mm:

  • File Tab -> Options -> Advanced Tab -> Display Section -> Ruler Units
  • Select Millimeters

To change the column/row width/height(in mm):

  • View tab -> Page Layout
  • Select all cells
  • Right-Click on Columns -> Column Width...
  • Right-Click on Rows -> Row Height...
  • Great answer. Only thing that could make it better would be some screenshots. – CharlieRB Apr 1 '14 at 15:35
  • Ran into 2 issues: -Couldn't print a "blank" page (I have grids on it). Adding a "." to the bottom, right hand square allowed it to print. -Excel apparently won't let you set a height/width of 4mm, it changes it to 3.97mm (small amount for 1 square, but over several, it gets way off). – BondUniverse Apr 1 '14 at 16:10
  • @BondUniverse Adding some spaces to cells should allow a blank page to be printed. As to the 3.97mm, I just looked and apparently Excel will round the number down to the nearest .265 mm. (.265*15=3.975) – user304064 Apr 1 '14 at 17:24
  • @bobSmith1432 While I really need a precise 4mm for my purposes, unless someone gives a better answer soon, I'll mark yours as accepted, chocking the rounding off to an annoying Excel limitation. – BondUniverse Apr 1 '14 at 17:57

Awesome way to abuse Excel! Seriously, I like it, I learnt something.

You might however be better served with something a Google search for "printable grid" and some scrolling turned up, I will let the URL speak:


They have roughly a cubic lightyear of grid-pdfs for free download. I hope A4 is alright for you, otherwise I suppose they have that on letter or whatever as well.

btw. at least your tags are a clear case of the XY-Problem. This is not an Excel-Question at all really. :-) Fortunately you stated your ultimate goal. Hope this gets you the precision you need.
