Childs bedroom size

What is a Good Size for a Child’s Bedroom?

Children come in all age groups from 1 day to 18 years old and over if they live at home. No two child’s bedrooms are the same and each girl & boy wants or requires there own space for sleep, interest and study.

A well laid out room and position of furniture is important in relation to the bedroom size and functional use, also depends if a child has a use of play room or spends a lot of time outside or away from the house. When children grow older they’ll require or want more privacy, especially if you’re son or daughter is introverted.

This page gives good size bedroom ideas (More generous) meaning a child has the space and bedroom functionality for daily living and not merely adequate.

A good child’s single bedroom size is (Young kids less space 10’ x 12’) (Older child single 14’ x 14’) or shared bedrooms older 18’ x 17’, younger kids 14’ x 14’. Good room size depends on how a child uses and live in the room on a daily basis, including study, sleep, hobbies, invited friends, furniture & space to move around.

Double room size for teenage daughter or son’s bedroom

One older child could benefit from a double bedroom 14 x 14 approximately that could include a lounge seating area instead of one defined bedroom space. A good size bedroom for a teenager daughter or son would benefit from an area of they’re bedroom distinctly separate from the bed, chest of drawers and wardrobe, possibly the other side of the room.

Put a study desk in the room as it’s important for you’re child to use for completing school or university assignments or homework. The table area could double as a surface to work on interests they have that require a flat surface.

Furniture space in a teenager or young girl or boy’s bedroom

All bedrooms have some furniture including stand alone wardrobe, bed/s, chest of drawers/dresser, bedside table, desk and chair. Each child’s room is different according to personality, hobbies, and storage requirements, how a boy or girl use the bedroom day to day and time spent in the room.

Walk in closets/wardrobe save a lot of space, although they are in a fixed position and are not moveable if you are looking to re-design you’re son or daughters bedroom.

One idea to help prevent injury is to keep a reasonable distance between a chest of drawers/dresser and a bed. Why? Stops children from climbing on top of the chest of drawers then leaping onto the bed to see how they’ll bounce. Yes, I did this as a child.

Bedroom space to move around and play

  • Sufficient or indeed a generous amount of floor space to move around in a girls & boys bedroom helps avoid accidents, such as tripping over toys, or constantly walking around furniture or other items in the bedroom.

Does you’re child have mobility issues, such as use of crutches or a wheel chair? Think about manoeuvrability getting in and moving around the bedroom.

Almost all children will invite friends over for a visit and they’ll stay for 20 minutes up to all day. Indeed some daughters bring 12-15 friends to they’re bedroom for a few hours to chat, study or activity games.

I have thought about bean bags or folding chairs to save space for my home use for additional seats for friends visiting, although some people will require sitting on the floor or the bed.

You could have a separate play area or children’s entertainment room or space where a child would require less space in they’re own bedroom spending time playing & meeting friends in a separate room, maybe around 13’ x 16 in size.

Single child or sharing a bedroom?

  • Positioning the beds correctly allows for enough space for other furniture, toys and for two children to play and move around comfortably, although the room requires to be an adequate size for age, number of children & use.

Two younger children sharing a bedroom could have bunk beds in the corner or positioned along one of the walls depending on the dimensions and shape of the room. You’re son’s or daughter’s can also choose to have twin separate or queen beds in the room so to move them around according to bedroom shape and use.

Consider age of children for good bedroom size

Young children 0 to 9 years old generally require less bedroom space and are reasonably happy in a smaller bedroom alone of around 10 x 12 with adequate space for a stand alone wardrobe, dresser/drawer chest and seat. 2 girl’s or boy’s sharing a bedroom a good size is 14 x 14 = 196 square feet for under 10 years old approximately. Lower age kid’s have more toys out on show, either on the floor, in baskets on shelves or other storage areas.

  • Good size floor area is required in a bedroom for young children to play on the floor.
  • Single or double bed according to the age and height of you’re son or daughter.
  • Younger children will invite less friends to the house at the same time possible than teenagers.
  • Older children tend to spend more time in a bedroom than younger aged children as young kids are more supervised by parents in play areas, kitchen or living room.

Twin or double beds in a child’s bedroom

Children of all ages 3 + years old are suitable for sharing a bedroom with twin beds in a 14 x 14 = 196 square feet room.  16 x 15 bedrooms will accommodate either two single or double beds, although 17 x 15 or 18 x 17 = 306 square feet would better for older children especially taller boys or girls. In the room you can also have 2 desks & chairs, chest of drawers and space to move around.

Children sharing a bedroom with twin or double beds require a larger room as more space is required for adequate room between bed, chairs, chest of drawers, desks and possible additional wardrobe storage that is stand alone in addition to any built in closet.

Storage space in children’s bedrooms

Maybe storage just outside the bedroom in a hallway or along a corridor can be used instead of a larger bedroom.

  • Shelves around the walls
  • Boxes or containers
  • Hanging baskets
  • Bedroom dresser with storage
  • Built in or walk in wardrobe
  • Bed with drawers or built-in storage

Area for hobbies and crafts

As children get older hobbies they have change or when they continue to take a keen interest in something that catches a 10 years old eye for 4 months require to be thought about.

  • Area to setup board games or play with action figures alone or with friends.
  • Bedroom space to set up a train set.
  • Separate desk for online gaming.
  • Area for an easel for drawing or musical instruments.

Children sleepovers

Almost all children will have friends visiting that will stay for 20 minutes up to all day. Indeed some boy’s or girls invite 2 close friends for a sleepover for a night or weekend. Floor space for sleeping bags, blow-up mattress or a sofa bed is beneficial for regular or occasional second or third child that wishes to sleep in a bedroom.

Save bedroom space by installing window seats in a child’s bedroom, especially in sharing twin rooms and when you’re son has many friend visiting regularly.

Space is utilized on the borders of a bedroom and less space is required and taken up using additional sofa or arm chairs for visitors.

One consideration is rectangular child’s bedrooms rather than a square area is better for furniture layout and functionality. Also think about alcoves, ceiling height and if the roof slants, like in some attic bedrooms.

Think about:  Do you intend staying in the home until you’re children have left for good? Consider the saleability of the house/flat or apartment to another family with the house bedroom sizes and shapes.


There is no one size bedroom for any age child in a single bedroom or sharing as children have they’re own interests and requirements at different stages of growing up. Although adequate space for functional furniture, play area, hobbies and entertaining friends will keep a child reasonably happy with the bedroom they’re in.

Children grow up and may require more bedroom space for changing interests or even spend less time in the bedroom.

Space for additional seats for friends visiting regularly or at short notice all parents should think about.

As parents we get to know the needs and wants of each child. Living habits and interests change over time and you can judge accordingly a good size bedroom for each child.
