Furniture Scale matters also for setting up a real room or for doll houses. If you choose furniture whose size matches the surrounding space, everything looks and feels more right. Scale keeps the right links between sizes in the space while proportion helps to match various parts.
Furniture with good scale truly does make the room more homely.
Choosing the Right Size Furniture
Proportions in a room do not depend only on the square area. The height of the ceiling, sizes of windows arches and doors all affect the whole. Also the link between the room and nearby spaces has weight, especially for the flow of folks.
It would be weird to lay a chair in the centre in front of heavy furniture. Even so that does not mean that every bit in the room needs the same weight or size. Such sameness would result in too heavy or too light space, that visually would look boring and odd.
Deciding the size of a sofa or coffee table to buy seems easy. Even so when various factors come into play, it becomes hard. A practical way is to avoid too big bits in little rooms and litlte bits in large ones.
When dealing with a picture above a bed or other furniture, it should cover at least half to two thirds of the wall space.
A practical method for planning a room is to design a floor plan to scale and use little models of furniture to test setups. Many folks measure there furniture with a tape and later print 3D little box shapes to show every piece. Using sturdy material, you have more choices than with paper, and the models are more lasting.
One can even recycle them for years, almost like homemade doll furniture.
Talking about miniatures, the scale of doll house furniture forms its own world. The most used scale is 1:12, which matches one inch to one foot. Sellers offer beds, kitchens, plates, tables, clocks, cabinets, pianos and more in that size.
There are also 1:24 half size versions and even 1:6 bits for bigger dolls. If the ceiling of a doll house measures four to six inches, it is probably 1:24. In a range of six to eight inches, it is possibly 1:18 or 1:16, sometimes called three quarter scale.
The IKEA Flisat doll house has almost the usual 1:12 size, which is based on the Queen’s doll house of Mary.
Before, people made sellable models of furniture in 1:4 or 1:10 scale, when travel was very limited. Those little samples showed the style and options of the maker to far away customers. At first 1:6 scale seemed fit for display models, like those that Vitra uses for chair sets.
But some bits reached two metres long, which made the scale less handy to carry. The advantage offurniture in any scale is that one can always move it around.
