Advice for choosing the right size bed frame

When shopping for a new mattress, you have the option of buying it with a frame, such as a divan bed, or separately. Many people prefer to choose their mattresses and bed frames independently, even from different manufacturers. It’s important to check the dimensions of your chosen frame to ensure it fits your room and can accommodate your mattress.

The style of the bed frame also matters. A divan base is a space-saving option as the mattress sits directly on top. However, wooden or metal bed frames can add a few extra centimeters around the edge. Fabric bed frames, like a roll-top or sleigh-style bed, take up more floor space and don’t sit flush with the wall. This can affect your layout and make opening wardrobe doors tricky.

How to Measure Bed Size

To measure your bed size accurately. Start at the headboard and use a tape measure to check the distance to the foot of the bed. Measure the width from side to side and the length from head to foot. These steps help confirm your bed matches common UK bed sizes in both width and length.

It’s important to ensure your new bed or mattress can be safely and efficiently delivered to your home and placed in the room of choice. Before making a purchase, use a tape measure, and, if needed, a protractor or angle finder, to confirm the space accommodates your choice. Taking key measurements ensures the purchase will fit perfectly and makes it easier to choose the right option.

Measure your Room

When buying a new mattress, it’s crucial to ensure it physically fits in your bedroom. Consider your furniture and the space available to move around the bed. Additionally, take into account the bed base. Divans are typically the same width and length as the mattress, but many bed frames are slightly wider or longer. Before you order, make sure to check the sizes of both the mattress and headboard to ensure everything fits properly.

Measure your Doorways

When buying mattresses, ensure they aren’t bent during delivery. Measure your front door and any doorways leading to the final space where the mattress will go. The doorway should be higher than the mattress width for a smooth entry. When measuring diagonally, also account for the mattress depth to make sure it fits through the space properly.

Measure your Stairway

At the tightest point, such as a staircase, measure the distance to any low ceilings. Check the clearance perpendicular to the stairs at a 90° angle to ensure it’s greater than the mattress width for a good fit. This will help avoid any scuffing. While measuring, also consider the height, being mindful of lampshades or other obstructions.

Measure any Corners

When navigating turns such as in stairs a hallway, or around a banister rail, measure the mattress length and depth to ensure it won’t need to be bent. Pro Tip: If the mattress can fit across the corner at a 45° angle, it should turn easily. This is also a great opportunity to remove any hanging pictures or mirrors that might be in the way.

Conclusion

From small singles for children to super king-size options for families, each bed size has its purpose and benefits.
