Measuring in the Round

The occasional wallcovering job will bring you face to face with a measurement nightmare.

  • What if you have to provide a mural that runs around all four sides of a room, and has to match up perfectly from starting edge to final edge?
  • What if you have to provide 4 sides of an interior wall and have the beginning and end of the mural match up?

This isn’t your momma’s dainty flower design that you can hack together in the corner above the door.  You have to be dead on to please the customer.

What do you do?

Measure, Measure, Measure

This type of project cannot be done with drawings, it has to be performed with real live measurements of the final wall finish.

For each of the four (or more) walls

  • Measure the breadth on the top
  • Measure the breadth on the bottom

All of these measurements should be accurate to the quarter inch or better.

Do the Math

OK, here is the hard part.  You have to come up with the exact right width of a mural that takes into account variations in the plumb of the wall, and variations in height and width for each wall.

This sounds like it will be hard, but there is a simple fact that makes it not so bad- you are building a mural that starts and stops at the same point- so there IS a correct answer.

  1. Add up the breadth on the top of each wall
  2. Add up the breadth on the bottom of each wall
  3. Determine which is larger- this is your overall mural width.

With an over all width, you figure your height based on your measurements, and you have your mural size.  IS this a perfect solution?  Unfortunately it is only as perfect as the plumb of the wall- and your print will be off by the plumb difference- that’s just a fact.  We’re doing the best we can here.

Special Bleed

Although it’s a good guess, When wrapping a room, The bleed on your starting edge is not exactly the image from the END of your image, and vice versa.  If the print does not match up perfectly, you will have a portion of the image that is duplicated.

Instead, determine a blurry, smeared, or ‘blank’ portion of the image that has a 1/4″ repeat, or constant image.  THIS should be the bleed.  Although the intention is to cut off ALL of this bleed, matching starting edge and final edge should be easy if they are the exact same pattern.

These are the techniques that we here at Lateral Art offer to our customers in producing accurate, right on graphics that no end customer would complain about.
