What Should You Consider Before Deciding Between a King and a Double Bed?

Budget

Both the bed and the mattress size have a significant impact on the cost. You also need to accessories your bed with blankets, sheets, foundation, bed frames that will add to the total expenses. So, fix your budget and that will help you decide between king size bed vs double.

Room size

Considering the king size bed measurements you will need a large room - at least 13 feet by 13 feet. It takes more space than a double bed that can easily fit in room size 9 feet by 9.6 feet. You must consider your room size and if placing the double bed vs king bed will leave the space for walking and furniture. Once purchased it is tough to replace!

Bed frame size

Some brands manufacture king size beds that are 3-5 inches wider than the king mattress sizes and the benefit is adequate support. Some bed frames like platform bed frames, solid wood frames, and sleigh beds can consume more room space. If you have space limitations you can buy a slim metal frame or any other frame size that is closer to the mattress size.

Sleep requirements

You need to consider the number of sleepers before buying a double bed or king bed. A double bed is sufficient for a single sleeper or two kids. For couples who want extra space to stretch out or move, a king size bed is an ideal choice. The next thing you should consider is your height. While a double bed size is best for those less than 6′ tall, a king bed is perfect for those more than 6′ tall (so they can sleep without their feet dangling).

Bottom line

A double bed is narrower than a king bed, but wider than a twin bed. While a double bed is worth buying for a single adult, king size is an ideal choice for couples and co sleepers. Buying a bed is an expensive endeavor and you want it to last long. Before buying a double bed vs king bed, you must consider your budget, room size, and personal sleep needs.
