How to Hang Wallpaper


Wallpaper is a great, versatile product that can be used throughout the home to add visual interest and sophistication to any room. Some homeowners prefer to decorate with paint for fear of not being able to hang wallpaper. But once you know how best to hang wallpaper, it’s a simple task that even DIY beginners can tackle.

This step-by-step guide is designed to show you how to hang wallpaper, so you can paper your walls to perfection.

Let’s get started with what you’ll need…





Before you start

Read our DIY Safety Tips, as this project requires the use of some tools and chemicals. Keep your space well ventilated, lay a protective sheet over your flooring and cover all switches and sockets with masking tape. Keep adhesives away from children, always use a suitable ladder and make sure you follow the manufacturer’s instructions when handling chemical products.


Measure the room

First, work out how much wallpaper you’ll need to hang to cover the whole room.

Measure the total perimeter of the room in metres (including doors and windows), then divide that by the width of the wallpaper.

Multiply the height of the room by the number of widths needed to get the total length of wallpaper required – and divide this by the length of a roll. This will give you the number of rolls you need.

Top tip: Buying an extra roll or two is always a good idea. Just keep hold of your receipt, so you can easily return any unused rolls.


Cut the wallpaper

Before you begin to hang wallpaper, it helps to cut the rolls down into manageable sections.

To do this, measure the height of your wall and add 10cm to this measurement to allow for trimming. Use wallpaper scissors to cut your first strip and then use the strip as a guide to cut the second, followed by the rest.

Top tip: If your wallpaper has a pattern on it, you can find out how to hang it properly further down the page.


Mix the wallpaper paste

Depending on which wallpaper paste you have, how you prepare it may be a little different. So, follow the manufacturer’s instructions for this step.


How to paste different types of wallpaper

Paste-the-wall wallpaper

Some wallpaper allows you to paste the wall rather than having to brush the strips of wallpaper with adhesive on top of a pasting table.

To hang paste-the-wall wallpaper, simply cover a section of the wall with your paste adhesive using a pasting brush and unroll the wallpaper from the top corner of the wall to the bottom. Carefully smooth out the wallpaper as you go down the wall with a wallpaper brush or smoothing tool. Trim any excess from the bottom.


Paste-the-paper wallpaper

To hang paste-the-paper wallpaper, place the wallpaper strips face down on a pasting table. Follow the manufacturer’s guidelines to make up the paste – and using upwards and outwards movements with a pasting brush, apply the paste to the back of the wallpaper.

If any paste gets on the patterned surface, sponge it off straight away. Fold the ends of the strip in towards the middle of the length, and then you’re ready to hang wallpaper.

Top tip: If needed, allow the pasted strip to ‘soak’ – meaning leave the wallpaper to expand to its maximum width once the adhesive has been applied. If you’re wondering how long do you soak wallpaper for, the soak time is normally indicated on the label, e.g. five minutes.


Top tips before you hang wallpaper

Make sure your walls are dry and smooth. If you’re wallpapering on plaster, sand the walls down and apply a universal primer. This will help the surface to get a good grip on the wallpaper.

If you are planning to wallpaper over paint, ensure the wall is in good condition and then wash with multi-surface soap, let it dry and add an acrylic primer before hanging wallpaper.


When to use lining paper

If your wall has imperfections, or you’re hanging embossed wallpaper, consider applying lining wallpaper before your decorative choice. This will ensure the surface is as smooth as possible.

Lining paper is usually applied horizontally to avoid the joins between the strips lining up with those of your decorative wallpaper. Wait 12 hours for the lining paper to dry before applying your decorative paper.


How to hang patterned wallpaper

If you want to learn how to hang wallpaper that has a pattern on it, start at the window and work out the way in both directions – towards the darkest corner of the room.

Using a plumb line, draw a vertical line with a pencil down the first wall you are going to paper. This will ensure your patterns stays straight.

Unfold the top half of the pasted length and press it gently against the top of the wall (allowing enough paper – about 50mm – to be trimmed off at the ceiling). Then, use a papering brush to smooth the length into place and remove any air bubbles.

To trim any excess paper, mark a line down the corner of the paper, ease the paper away from the wall and trim it with scissors. Brush the paper back into place.

For the second strip of wallpaper, place it next to your first and smooth it into place as before. Make sure you create a seamless butt joint and match the pattern as you position each subsequent strip.

Top tip: If your design has a large pattern, start at the centre of a feature such as a chimney breast or main wall. Before cutting wallpaper with a large pattern on it, make sure you will be left with a full motif at the top of the wall.  Keep any extra pieces you cut off for above doors and windows.


Dealing with obstacles when hanging wallpaper


Hang the wallpaper from the top of the wall, smoothing it down as far as the architrave.

Use scissors to make a diagonal cut into the corner of the architrave and push the paper in. Crease the waste along the architrave using scissors and then roll back the paper and trim off the waste.



Treat the top part of the window surround like a door.

To cut around the windowsill, make a horizontal cut up to the top corner of the sill. Then, make a diagonal cut into the bottom corner of the sill. Feel for the end of the sill and make a series of cuts up to this line. Use the brush to force the paper into the angles made by the wall, the architrave and the windowsill. Mark and trim the waste.


Light switches and power sockets

Turn off the electricity for the circuit at the mains. Hang the covering as normal, then make diagonal cuts from the centre of the light switch or power socket plate to its corners. Trim the waste, leaving 6mm extra.

Loosen the screws, holding the faceplate, and tap the paper under the plate. Tighten the screws and wait for the paper to dry before switching the electric back on.

Carefully tear 25mm off the overlap and flatten it round the corners with a brush. The torn edge, when covered, will show less obviously than a straight cut line.

Hang the full-length piece and make a horizontal cut with the scissors where the piece hangs over the opening. Fold the overlap into the reveal, up to the frame – crease and remove the waste.
