So I’ve been installing these wall decals in kids’ rooms for like three years now and honestly, there’s so much nobody tells you upfront. My neighbor texted me last week asking which ones to buy and I ended up sending her like 47 voice messages, so let me just dump everything here.
The Quality Thing Nobody Mentions
First off, not all removable stickers are actually removable. I learned this the hard way in my nephew’s room where we used these cheap ones from that random Amazon seller and they left this gross residue that took forever to get off. You want vinyl decals specifically, the fabric or paper ones are gonna be a disaster. The vinyl ones have this matte finish usually and they feel slightly textured, not like sticker-sticker if that makes sense.
The brands I actually trust: RoomMates is solid, they’re at Target and online everywhere. WallPops are good too. Jungle Stickers if you’re in the UK. I’ve used probably 30+ different sets at this point and these don’t leave marks when you peel them off. Which you WILL be doing because kids change their minds every six months about what they’re into.
Wall Prep Is Everything
Okay so this is gonna sound obvious but you need to actually prep the wall and most people skip this step. Your wall needs to be:
- Clean – wipe it down with just water and a tiny bit of dish soap, no harsh cleaners
- Completely dry – wait like 30 minutes after cleaning
- Not freshly painted – this is the big one, you need to wait at least 2 weeks after painting, I usually say a month to be safe
- Flat or eggshell finish – textured walls are a nightmare, the stickers won’t stick properly
I made the mistake once of putting decals up in a room that was painted like 10 days before and when we removed them a year later, they pulled the paint right off. Had to repaint the whole wall. My client was really nice about it but I felt terrible.
Actually Choosing The Stickers
This depends on what kind of chaos level you’re dealing with. If the kid is under 5, go with the peel-and-stick repositionable ones that come in sets. The individual pieces you can arrange however you want are better than the big scene decals because you can space them out as the kid grows and redecorate without buying all new stuff.
Themes that actually last: space stuff, animals, trees and nature, geometric shapes. My daughter went through a phase with unicorns and I’m SO glad we went with the repositionable individual ones because we moved half of them around when she decided she wanted a “forest” instead. Just shifted some unicorns to her closet door and added tree decals.
Skip the licensed character stuff unless you’re prepared to redo it in like 8 months. Frozen, Paw Patrol, whatever – kids move on fast and those stickers are usually more expensive anyway.
Size Matters More Than You Think
Everyone buys stickers that are too small. You’re looking at them online and thinking “oh that 24 inch tree will look great” and then it shows up and looks tiny on an actual wall. I usually go for:
- Main focal pieces: at least 36 inches for one dimension
- Accent pieces: 12-18 inches minimum
- Tiny details: 4-6 inches but you need like 20 of them to make an impact
There’s this measuring trick I do – take painter’s tape and actually tape out the dimensions on the wall before ordering. Sounds extra but it saves you from that disappointed feeling when the package arrives.
The Installation Process
Okay so you’ve got your stickers, wall is prepped, now what. First thing – don’t do this when you’re tired or rushed. I tried installing a whole jungle scene at like 9pm once after a long day and had to redo half of it the next morning because nothing was level.
Start with your biggest piece first and work outward. Use a level app on your phone or an actual level, especially for things like tree trunks or tall buildings. The small stuff you can eyeball but anything vertical needs to be straight or it’ll drive you crazy every time you look at it.
The Actual Technique
Most decals come with transfer paper on top. You’re gonna peel the backing off first – do this slowly, sometimes the sticker wants to stick to the backing instead of the transfer paper and you gotta coax it.
Position it on the wall where you want it. This is where repositionable really matters because you can adjust. Press the middle first, then work your way out to the edges. Use something flat to smooth it – I use an old credit card, some people use those squeegee things. You’re pushing out air bubbles and making sure all the edges are down.
Then you peel off the transfer paper. Go slow, at an angle. If you see the sticker starting to come up with the transfer paper, press it back down and try again.
Wait I forgot to mention – temperature matters. Don’t install these when the room is super cold, the adhesive doesn’t work as well. Room temperature or warmer is ideal.
Common Mistakes I See All The Time
Putting stickers too high. I get it, you want them visible, but kids actually like having things at their eye level. Put some lower than you think you should. My son used to sit on his floor and just stare at the animal stickers we put down near the baseboard.
Overcrowding the wall. More is not better with these. You need negative space. I usually cover like 30-40% of one wall max, sometimes just one corner. Otherwise it looks chaotic and busy, which is not great for a room where a kid needs to sleep.
Not planning the layout first. Lay all your stickers out on the floor in roughly the arrangement you want before you start sticking anything. Take a photo of it. This is your reference guide.
Oh and another thing – those “growth chart” stickers are cute but only if you’re gonna actually use them. Otherwise they’re just taking up prime wall real estate.
What About Textured Walls
Ugh okay so if you have textured walls, your options are limited. The stickers won’t lay flat and edges will peel up over time. You can try:
- Using a hairdryer on low heat while pressing the sticker down – helps it conform to texture
- Going with smaller decals that have less surface area
- Accepting that they might not last as long
- Actually just painting a smooth section of wall first and putting stickers there
I had a client with that knockdown texture and we ended up painting one wall smooth. It was extra work but the stickers looked so much better and actually stayed up.
Mixing Different Sets
This is where it gets fun. You don’t have to buy one complete set and call it done. I mix sets all the time. Like we did this one room with:
- Cloud decals from RoomMates
- A hot air balloon set from Etsy
- Some birds from WallPops
- Individual star stickers
The trick is keeping the color palette consistent. Stick to like 3-4 colors max that all work together. Most decal sets list their colors so you can match before buying.
My cat just knocked over my coffee sorry, anyway –
Removal Process
Eventually you’re gonna need to take these down. Maybe you’re moving, maybe your kid is 12 now and doesn’t want cartoon animals anymore. The removal is actually easier than installation if you do it right.
Start at a corner or edge and peel slowly at a 45-degree angle. Not straight out, not straight down – at an angle. Go slow. If it’s not coming off easily, use a hairdryer on medium heat to warm up the adhesive. This makes it release better.
If you do get residue (it happens sometimes especially with cheaper stickers), use:
- Goo Gone – works but smells terrible
- Rubbing alcohol on a cloth
- Warm soapy water and patience
Don’t use anything too abrasive or you’ll damage the paint underneath.
Storage If You’re Reusing Them
Some decals you can reuse if you’re careful. When you peel them off, stick them onto wax paper or parchment paper. Roll it up loosely, don’t fold or crease. Store flat if possible. They lose some stickiness so they might not work on textured walls the second time, but they’re usually fine on smooth walls.
I’ve reused decals between my kids’ rooms and it works maybe 70% of the time. The edges might not stick as well but you can use tiny pieces of poster putty to help if needed.
Budget Breakdown
Since you’re probably wondering what this actually costs:
Small accent set (like 20 pieces): $15-25
Large statement decals: $30-50
Full room sets: $50-100+
Custom decals from Etsy: $40-150 depending on size
You can do a really nice room for under $75 if you’re strategic. I usually tell people to buy one larger set and one or two smaller complementary sets.
The expensive custom ones from Etsy are worth it sometimes – we did a custom name decal with some woodland creatures for my niece’s room and it’s held up for three years now, still looks perfect. Sometimes spending $80 once is better than buying cheap sets multiple times.
Where To Actually Buy Them
Target and Amazon are obvious but the selection is hit or miss. Etsy has tons of options and you’re usually supporting smaller shops which is nice. Wayfair has a decent selection. If you’re in the UK, Dunelm and Next have good options.
Watch for sales – RoomMates stuff goes on sale at Target constantly. I’ve gotten sets for like 40% off by just waiting a few weeks.
Lighting Considerations
This is gonna sound weird but think about how light hits the wall. Glossy decals can create glare if they’re opposite a window. Matte finishes are better for most situations. Also, those glow-in-the-dark ones? They need to “charge” from light exposure, so they work best on walls that get decent daylight or are near the main light fixture.
We put glow stars above my son’s bed and they barely glow because that corner doesn’t get much light. Would’ve been better on the ceiling near his overhead light.
Rental-Friendly Tips
If you’re renting and paranoid about damage:
- Test one small decal in an inconspicuous spot first, like inside a closet
- Take photos when you install them to show you didn’t damage anything
- Avoid putting them over any existing wall damage, landlords love to blame stuff on you
- Keep all packaging and instructions to prove they’re removable
I’ve never had an issue with landlords and decals but I’m also really careful about the brands I use and the removal process.
Quick Fixes For Common Problems
Edges peeling up: press them down with your thumb and hold for 30 seconds, or use a tiny dab of poster putty behind the edge
Sticker won’t stick: wall might be dusty or the room’s too cold, try cleaning again and warming the room up
Air bubbles: poke them with a pin and smooth the air out toward the hole
Sticker stuck to backing paper: carefully separate them with your fingernail, go slow
Colors don’t match the photo online: this happens a lot, especially with cheap sellers, read reviews with photos before buying
The reality is these things are pretty forgiving. I’ve messed up installations and fixed them. Kids don’t notice if something’s not perfectly level. The whole point is making their room fun and personal without permanent commitment.
Just measure twice, go slow on installation, and don’t overthink it too much. Start with one wall, see how it looks, add more if you want. You can always add but removing and repositioning is annoying so better to start minimal.
