Print a classroom bulletin board poster

Teachers often need a big picture for a bulletin board: a map of the world, a number line, a seasonal tree or a character from a book. School printers handle Letter or A4 sheets. This tool splits a picture over as many sheets as you need.

A common bulletin board is 36 x 48 inches, or 3 x 4 feet. A 36 inch wide picture takes 5 sheets across on Letter paper. A 24 inch wide picture takes 4. A 36 x 24 inch piece takes 15 sheets in all. The tool is set to 36 inches wide. Change the width to match your board.

Most home printers cannot print within 0.25 in (6 mm) of the edge. The overlap is the strip you glue.

 

 

Sheets for common bulletin board pieces

These counts use a 0.25 inch printer margin and a 0.5 inch overlap. The tool above shows the exact numbers for your picture.

Let students do the gluing

A tiled poster is a good group job. Give each student or pair one sheet to color or decorate before the sheets are joined. The labels (A1, A2, B1) tell them where their piece goes. Print a clean copy for the board, and let the class color a second set.

Save toner and paper

  • Use a drawing with a white background. Large colored areas use a lot of toner.
  • Turn off the assembly map page for classroom sets.
  • Use the test page button to check the size before you print 20 copies.

Borders and titles

For a border, make a long strip. Set the height to one page and see the Banner page for details. For a title, use a wide picture of the words and make it 8 inches tall.

Print at actual size

In the print dialog, choose 100% or Actual size. Do not choose Fit to page. That setting shrinks every tile, and the pieces will not line up. Print the test page first and measure it.
