Why Bed Size Matters
Choosing the right bed size is one of the most important decisions you'll make when furnishing your bedroom. The right size ensures you get a comfortable night's sleep, makes the most of your available space, and looks proportionally right in your room.
In the Republic of Ireland, we use standard bed sizes that are consistent across most retailers. This guide will help you understand each size, who it's best suited for, and how to measure your room to ensure your new bed fits perfectly.
💡 Quick Tip
Always measure your room before purchasing a bed. Consider door swings, wardrobe access, and walking space around the bed.

Bed Frame vs Mattress Size
It's important to understand that bed frames are typically slightly larger than the mattress they hold. This is because the frame needs to accommodate the mattress while also providing structural support.
Bed Frames
Add 5-15cm to mattress dimensions for frame width. Headboards and footboards add extra length.
Ottoman Beds
Ottoman storage beds need extra clearance at the foot or side to open the storage mechanism.
What to Check Before Buying
- Product dimensions: Always check the full product specifications, not just the mattress size label
- Headboard height: Consider ceiling height if buying a tall headboard
- Footboard: Some frames extend beyond the mattress length
- Storage beds: Ottoman and drawer beds need clearance space to open
How to Measure Your Bedroom
Follow these simple steps to ensure your new bed will fit perfectly in your room:
Measure the room dimensions
Use a tape measure to record the length and width of your room in metres or centimetres.
Note door swing areas
Mark where doors open into the room. The bed shouldn't block door access.
Check window positions
Consider window locations – avoid blocking natural light or radiators beneath windows.
Allow walking space
Leave at least 60-90cm around the bed for comfortable movement and making the bed.
Consider other furniture
Account for wardrobes (need door clearance), bedside tables, and dressing tables.
Check access route
Measure stairways, corridors, and doorways to ensure the bed can be delivered.
Pro Tip: Use painter's tape or newspaper to mark out the bed dimensions on your floor. This gives you a visual representation of how much space the bed will take up.
