About RajaSofa

Buying a sofa is deceptively hard. It is one of the biggest, most-used things you will put in your home, it has to travel through your front door to get there, and you usually commit to it from a showroom floor or a photograph without knowing whether it will actually fit the room, suit your height, or last. The questions that decide whether you love it or regret it — how long a sofa the wall can take, how deep the seat should be for you, how much fabric a re-cover needs, whether the layout leaves room to walk — are all answerable with a tape measure and a little arithmetic. Doing that arithmetic by hand, for every option you are weighing, is where it turns into a chore.

RajaSofa exists to take that measuring and estimating off your plate. Rather than long articles you have to read end to end, the site is built around small, single-purpose calculators, each aimed at one decision. The Sofa Size Calculator works out the longest sofa a wall can take while leaving a walkway, and checks whether a sofa you like will fit the room and clear the doorway on its way in. The Seat Depth Advisor turns your height into an upright-to-lounge seat-depth range, with guidance on back cushions, because depth is the measurement people most often get wrong. The Living Room Layout Plannerchecks that a sofa and coffee table fit together with comfortable clearances — roughly a 45 cm gap to the table and a 75 cm walkway — and tells you how much open floor is left.

Three more tools cover the practical side of owning and reupholstering a sofa. The Sofa Fabric Yardage Calculator estimates the upholstery fabric to recover a loveseat, three-seat sofa, or sectional from its length and a pattern-repeat allowance, in yards and metres. The Cushion Foam Calculator turns cushion dimensions and a count into a foam volume in cubic metres and board-feet, plus the finished mass at a density you choose. And the Sofa Cost Per Use Calculator spreads a sofa’s price across its expected life and daily use so you can compare two options on the same footing — often the dearer, longer-lasting one is the cheaper choice.

Beyond the calculators, the blog and learn section cover sofa buying, sizing, upholstery and fabric care, styles, and living-room layout, and explain the reasoning behind the numbers the tools produce. The museum is a browsable, illustrated collection about the sofa and the furniture of the living room, with its entries, images, and facts drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. RajaSofa is an independent site, not a retailer, and not affiliated with any furniture brand, manufacturer, or standards body it may mention. It is supported by advertising, which is how the tools stay free with no account required. Every figure the tools produce — a recommended length, a seat-depth range, a fabric or foam quantity, a cost per use, a layout fit — is a general estimate for planning, built on the measurements you enter and common furniture conventions. It is not professional interior-design advice. Measure your own room, doorways, hallways, and turns, and sit-test where you can, before you buy. If a tool looks wrong, or there is a calculator you wish existed, the contact page is the place to say so.
