Unless I am mistaken, there is no way to change the checkbox size and border properties. I have read through many Access programming books and I distinctly remember at least one of them saying that if you needed to change the properties (ie size and look) of a check box, you would have to create them your self....Here has been my solution:
Create a text box and set the font size to that which you want. Place one x in this box (ie your check will now be an x but this is usually acceptable to everyone). Once you have it all right, name it something like txtChecked.
Copy this text box and remove the x. Name this box txtUnchecked.
In the OnClick property of txtChecked, put the following:
Me![txtChecked].Visible = False
Me![txtUnchecked].Visible = True
In the OnClick for txtUnchecked, simply change the trues and falses around.
The last piece of the puzzle is that you have to check which box is visible whenever you need to use this....
Seems like a lot of work, but once you have the first one done, it comes along pretty easily. I have an example database with this inn it if you like....just send an email to the address in my profile and I will forward it to you. Good luck and let me know if I can help anymore. It's not important that someone else can do in one step what it took you ten to do...the important thing is that you found a solution.
