In Word:
click on Tools
click on Letters and Mailings
click on Envelopes and Labels
click on the tab for Labels
click on Options - find a label that measures the size you are looking for; these are arranged by company and type, so there are lots of choices
click on okay
click on New Document
You will be taken back to your Word document but you will see faint lines on the page. These lines denote your label edges and you can put what you like into the first one, then copy and paste it into the rest. Easy!!
