A 118 x 79 in play mat is a big piece of floor. That is the whole point for some families, and a real worry for others. If you are standing in your living room trying to picture almost ten feet of mat in front of the sofa, this guide is for you.
We will look at how big that size really is, when it works beautifully, when it is honestly too much, and a few layouts that tend to work in larger rooms. We sell this size, so we will also be upfront about when a smaller mat is the better choice.
How big is 118 x 79 in, really?
Numbers on a product page are hard to picture, so here is the same size a few ways:
- In feet: about 9 ft 10 in long by 6 ft 7 in wide.
- In centimeters: about 300 x 201 cm.
- In area: about 64.7 square feet.
For comparison, our other two sizes are 79 x 59 in (about 6 ft 7 in by 4 ft 11 in, roughly 32.4 square feet) and 50 x 50 in (about 4 ft 2 in square, roughly 17.4 square feet). So the 118 x 79 in mat covers about twice the floor of the 79 x 59 in, and nearly four times the 50 x 50 in. Every size is the same total thickness, about 1.3 in (3.3 cm), so choosing the large one gives you more space, not a thicker mat.
The fastest way to make this real is to mark it out. Use painter's tape or a few towels to outline a 9 ft 10 in by 6 ft 7 in rectangle where you would put it, then live with the outline for a day. Our room-measuring guide walks through this step by step, and the Playmat Size Guide lists all three footprints side by side.
A quick fit check for the large size
Before you choose 118 x 79 in, compare these numbers with your own floor:
- Clear length: you need about 9 ft 10 in in one direction, plus any walkway you want to keep.
- Clear width: you need about 6 ft 7 in in the other direction, plus room for door swings.
- Both numbers matter: a long, narrow space can have the same area as a wider one and still not fit the mat.
- Not enough room? The 79 x 59 in size is about 6 ft 7 in by 4 ft 11 in, and 50 x 50 in is about 4 ft 2 in square.
The Playmat Size Guide puts all three footprints side by side, and you can see current options for each size on the GRHomera Playmat product page. If you are still comparing, browse our baby play mats.
When a large play mat makes sense
The big size earns its floor space when you have the room and will actually use the extra area. It tends to be a good fit if:
- Your baby is crawling, or will be soon. Crawlers travel, and a small mat can quickly become a launch pad your baby crawls straight off. The CDC's milestone tips for around 9 months suggest putting toys on the ground or play mat a little out of reach so your baby can crawl or scoot to get them, and a longer mat gives you room to do that without the toy ending up on bare floor. Our crawling guide covers what that stage usually looks like.
- More than one person plays on it. A parent lying beside a baby, an older sibling building blocks at one end while the baby rolls at the other, or a grandparent sitting with a toddler all take up room. A bigger mat means adults can get down on the floor comfortably too.
- You want one main play zone. Some families prefer a single, generous space in the living room instead of moving a small mat around the house.
- Your floors are hard and the room is open. On hardwood, tile or laminate, a large mat defines the play area clearly. If you are weighing it against a rug, see our play mat vs area rug comparison.
When 118 x 79 in is too big
Bigger is not automatically better. The large size is probably the wrong choice if:
- It would cover a walkway. If people have to step onto the mat to get from the hall to the kitchen, it will get walked on with shoes, kicked out of place and feel like an obstacle. Leave clear routes around it.
- A door would need to open over it. The mat is about 1.3 in thick, so check that any door near the play spot can swing freely without catching the edge.
- The edges would end up under furniture. A mat should lie flat. If the only way to fit it is to tuck the edges under a sofa, TV stand or radiator, a smaller size will look and work better.
- You need to move it often. If the play spot changes daily, between rooms or floors, a 79 x 59 in or 50 x 50 in mat is simply easier to handle.
- Your baby is a young newborn and space is tight. Early tummy time needs only a small patch. You can always size up later.
If any of these sound like your home, compare the 79 x 59 in size, or read our guide to setting up a play area in a small living room.
Layout ideas for larger rooms
Here are a few layouts to try with your tape outline before you commit.
1. Long side against the sofa
Place the mat's long edge parallel to the sofa, with a little gap so the sofa does not sit on it. Parents can sit on the sofa or slide down onto the mat, and the far side stays open for crawling. This keeps the mat out of the main walking route in many living rooms.
2. Tucked into a corner
Running the mat along two walls in a corner gives you a defined play nook and keeps the middle of the room free. It works well in L-shaped living spaces or a corner of a large family room. Check that outlets, cords, heaters and anything climbable are out of reach from the mat.
3. Centered as the room's "rug"
In an open-plan room, the mat can sit in the middle of the seating area, the way an area rug would. This works when the walkways go around the seating area rather than through it. Pick a color that suits the room: our Beige vs Dark Grey guide covers how each looks with different floors and furniture.
4. Dedicated playroom or bonus room
If you have a spare room, the large mat can cover most of the floor while you keep shelves for toys around the edges. Low, sturdy storage that cannot tip is the usual choice; anchor furniture as the manufacturer recommends.
5. Along a wall in a long, narrow room
The mat is a long rectangle, so it can line up along one wall of a long room, leaving the other side for walking. Measure the width carefully: you need about 6 ft 7 in for the mat plus your walkway.
A quick example
Say your living room is 12 ft by 15 ft. Twelve feet is 144 in, so if the mat runs its 118 in length along the 15 ft wall, the 79 in width leaves about 65 in (roughly 5 ft 5 in) across the room for the sofa, a walkway and anything else. Whether that works depends on your furniture, which is exactly why the tape outline helps. Measure your own room; this is only an illustration.
Practical notes before you order
- Allow space to unpack. The mat arrives compressed and takes 3-5 days to fully expand after unpacking, so you will want somewhere it can lie flat for a few days. Our guide to the first days after unpacking explains what to expect.
- Same features, bigger footprint. Every size has the same coral fleece surface, about 1.3 in (3.3 cm) total thickness and non-slip backing, in Beige or Dark Grey.
- Price. Weigh the cost of the largest size against the floor space you will actually use. You can compare current prices for all three sizes on the GRHomera Playmat product page.
- Care. A larger mat is more to clean, so follow the care label and our memory foam mat care guide.
Whatever size you choose, a play mat is for awake, supervised play, not for sleep. Measure first, outline the size in tape, then compare the finished dimensions in the size guide before you order from the product page.
FAQ
How big is a 118 x 79 inch play mat in feet?
About 9 ft 10 in long by 6 ft 7 in wide, or roughly 64.7 square feet. In centimeters, that is about 300 x 201 cm.
Is the large play mat thicker than the smaller sizes?
No. All three GRHomera sizes have the same total thickness, about 1.3 in (3.3 cm). The large size gives more floor coverage, not more height.
What room size do I need for a 118 x 79 inch mat?
There is no single answer, because furniture and walkways matter as much as the room's dimensions. Mark out the mat with tape, then check that walkways stay clear, doors can open, and the edges do not end up under furniture.
Should I buy the large size for a newborn?
Not necessarily. Young babies need only a small area for tummy time. The large size makes more sense once your baby is rolling and crawling, or if several people will play on the mat together.
