How to Measure Bed Frames and Mattresses for Your Bedroom: A Step-by-Step Guide

Whether you're upgrading your bedroom, furnishing a guest room, or just indulging in the joys of shopping for a new bed, we’re here to make the process simple and stress-free. At International Furniture in Andover, we know choosing the right bed frame and mattress is about more than just style—it’s about finding the perfect fit, both for your comfort and your space.

Here’s your go-to guide for measuring bed frames and mattresses to ensure they suit your bedroom like a dream. Grab your measuring tape, and let’s get started!

Step 1: Measure Your Room

Before diving into mattress sizes or bed frames, you’ll want to know the space you’re working with.

Clear the Area: Remove clutter, rugs, or furniture that may block your walls—this ensures your measurements are accurate.
Measure the Room Dimensions: Use a tape measure to calculate the length and width of your room. Note any unique features, like wardrobes, windows, built-in shelves, or radiators, which will affect furniture placement.
Check Ceiling Height: If you love the look of a canopy or tall headboard, make sure your ceilings are high enough to accommodate your dream design!

Tip: Measure in multiple areas, especially if your room isn’t a perfect rectangle. Double-check everything—it’s always better to be safe than sorry.

Step 2: Choose Your Mattress Size

From the space-saving small single for solo sleepers or kids, to the roomy super king and emperor mattress for maximum sleep space luxury, find the ideal fit for your bedroom.

  • Cot Size Mattress: Cot Bed. W 60cm x L 120cm
  • Toddler Size Mattress: Toddler Bed. W 70cm x L 140cm
  • Small Single Mattress: 2'6 Small Single Bed. W 75cm x L 190cm
  • Small Single Mattress: 2'6 Euro Small Single Bed. W 75cm x L 200cm
  • Single Mattress Size: 3'0 Single Bed.  W 90cm x L 190cm
  • Small Single Mattress: 3'0 Euro Small Single Bed. W 90cm x L 200cm
  • Small Double Mattress: 4'0 Small Double Bed. W 120cm x L 190cm
  • Double Mattress Size: 4'6 Double Bed. W 135cm x L 190cm
  • King Size Mattress: 5'0 King Bed. W 150cm x L 200cm
  • Super King Mattress: 6'0 Super King Bed. W 180cm x L 200cm
  • Emperor Mattress: 6'6 Emperor Bed. W 200cm x L 200cm

Tip: Bring your room measurements from Step 1 into account. For example, even though a king-size bed is luxurious, it might not leave room for bedside tables or walking space in smaller bedrooms.

Step 3: Measure Your Bed Frame

Every bed frame is unique—sleek platform beds, elegant upholstered designs, or timeless metal bed frames and wooden frames can vary significantly in size. Here’s what to measure:

Length and Width: Lay your frame flat and measure its outer edges. Make sure the dimensions match the mattress size you’ve chosen!

Height: Consider how high the bed sits off the floor. If you need extra storage, look for a frame with under-bed space. If accessibility is a concern, opt for a lower height.

Headboard and Footboard: These add extra inches to your frame and should be measured as well.

Tip: Don’t forget to measure doorways, staircases, and hallways too! You’ll want to be sure the bed frame can make it into your bedroom.

Bed Types

  • Adjustable beds - Elevate your head/legs at the touch of a button.
  • Bunk beds - Great for siblings or those who share a bedroom. These are a great space saving solution.
  • Cot beds – For adjustable cots that grow with your child, with handy height adjustments & teething rails.
  • Divan bases - Simple bed bases with storage drawers. Options to add a decorative headboard.
  • Guest beds – For the perfect night’s sleep for your guests.
  • Kids beds - A range of fun and practical beds, suitable for toddlers to teenagers.
  • Metal beds - Strong and sturdy bed frames with timeless appeal.
  • Ottoman / storage beds - Store your belongings beneath the bed base for ultimate space saving.
  • Upholstered beds - A range of luxurious fabrics in various colourways.
  • Wooden beds - Wooden finishes such as oak and pine for a rustic and natural finish to your bedroom.

Bed Base Types

  • Platform top - A strong, sturdy base consisting of a timber frame and a solid panel top.
  • Sprung slat - Curved slats, placed in multiple columns, offering more shock absorption with cushioned support.
  • Solid slat - Timber slats that run across the full width of the bed for a firmer, solid foundation for your mattress.
  • Adjustable - Adjustable position for a comfortable night's sleep, help relieve pain, and ease getting in and out of bed.
  • Sprung divan - Divan base with a top layer of springs running edge to edge, acting as a shock absorber, offering cushioned support and a softer sleep surface.

Step 4: Account for Comfort and Functionality

Your bedroom should be both beautiful and functional. Here are some things to consider:

Spacing Around the Bed: Aim to have at least 60- 76cm of walking space between your bed and the walls or other furniture. This ensures you’re not bumping into things in the middle of the night!

Furniture Layout: If you’re adding bedside tables, dressing tables, or benches, make sure they fit comfortably alongside your bed.

Future Additions: Are you planning on adding a guest chair or replacing a wardrobe later? Leave room for flexibility in your layout.
