There's no one-size-fits-all answer when trying to determine a reasonable furniture budget. Your individual needs, stylistic preferences, and the space you're working with are all factors to consider. 

The general rule is to allocate 5%-15% of your home's value to furnishing it. For example, for a $300,000 home, it's reasonable to spend between $15,000 and $45,000 on furnishings to cover every room.

Also, remember that investing in high-quality furniture for crucial pieces such as sofas and beds will ensure long-term durability. The key to a good furniture budget is balancing high-quality pieces that last longer with more affordable items you can replace or upgrade over time.

The measurements you use when discussing furniture sizes are any piece's three dimensions: length, width, and height.

Length accounts for the longest side of the furniture, and is particularly important for pieces such as sofas and dining tables. The width (sometimes called depth) measures from the front to the back, telling you how much floor space a piece of furniture will occupy against a wall. Finally, furniture height reveals how tall it stands from the base to the top, a key feature for storage pieces such as bookcases or wardrobes. 

You should also consider the furniture's weight for delivery and installation purposes. 

While the choice of color depends significantly on personal style and the existing palette of your space, some popular furniture colors currently in style reflect larger design trends.

Natural and earthy tones that bring calm and tranquility to spaces are popular. These could include shades of green, blue, and beige. Also, neutral colors such as gray, white, and black are timeless, offering the most versatility in design styles while maintaining their elegance.

Jewel tones are also popular for something more dynamic. Colors such as emerald green, sapphire blue, and ruby red are in vogue, adding a touch of luxury and vibrance to a space.
