Indian Home Textile Sizes & Measurements.

Measure the mattress itself, not the bed frame, and record three numbers: width, length and depth (height). Use a tape across the bare mattress at its widest and longest points, then measure the depth from the top surface to where it meets the base — Indian mattresses commonly run 6–10 in (15–25 cm), and a thick mattress or a mattress topper needs a deeper duvet cover or fitted sheet than a thin one. Write the numbers in both inches and cm before you shop. SOISU duvet cover sets are made for Indian Queen and King beds, priced ₹17,085–₹22,772.

"18×18" means 18 inches by 18 inches — a 45×45 cm square, which is the most common cushion size in Indian homes. The other standard is the lumbar or rectangular cushion at 12×18 in (30×45 cm), used behind the lower back or as the odd one out in a set. Larger 20×20 in (50×50 cm) and 24×24 in (60×60 cm) covers appear on deep-seat sofas. SOISU makes cushion covers in exactly two sizes — 45×45 cm (18×18 in) square and 30×45 cm (12×18 in) lumbar — across 295 designs, ₹1,361–₹6,826.

Measure the seat depth and the backrest height first: a sofa with a backrest under about 45 cm (18 in) will swallow an 18×18 in cushion, so use lumbars there instead. As a rule, a two-seater takes three cushions, a three-seater takes five, and an L-shaped sofa takes five to seven. Odd numbers look composed; even numbers look symmetrical and formal. Keep the total width of the cushions to under about half the sofa's width so the seat is still usable. Mix sizes — pairs of 45×45 cm squares with a single 30×45 cm lumbar in the middle is the most reliable arrangement.

The common sizes are 3×5 ft (91×152 cm), 4×6 ft (122×183 cm), 5×8 ft (152×244 cm), 6×9 ft (183×274 cm), 8×10 ft (244×305 cm) and 9×12 ft (274×366 cm). Use 3×5 or 4×6 as an accent — bedside, entryway or under a single chair. 5×8 suits a compact Indian living room where only the sofa's front legs sit on the rug. 6×9 and 8×10 anchor a full seating group with all front legs on. 9×12 fits a large living or dining room where the whole set sits on the rug. When in doubt, size up — an undersized rug makes a room look smaller.

Measure the seating group, not the room. Mark out the rug's footprint on the floor with masking tape or newspaper, then check three things: at least the front legs of every sofa and chair should sit on the rug; the rug should extend beyond the coffee table on all sides; and you want roughly 45–60 cm (18–24 in) of bare floor between the rug's edge and the wall. In a dining room, the rug must extend about 60 cm (24 in) beyond the table on every side so chairs stay on it when pulled out. Live with the tape outline for a day before ordering.

One inch equals exactly 2.54 cm, and one foot equals 30.48 cm. The conversions worth memorising: 12 in = 30 cm; 18 in = 45 cm; 20 in = 50 cm; 24 in = 60 cm; 3 ft = 91 cm; 5 ft = 152 cm; 6 ft = 183 cm; 8 ft = 244 cm; 9 ft = 274 cm; 12 ft = 366 cm. So an 18×18 in cushion is 45×45 cm, a 12×18 in lumbar is 30×45 cm, and a 5×8 ft rug is roughly 152×244 cm. Indian listings mix both systems freely, so convert before comparing two products.

GSM is grams per square metre — the weight of a fabric or the pile density of a rug — while thread count is the number of threads woven into one square inch of fabric. Higher GSM means a heavier, denser, usually more durable textile: it is the more honest number for rugs, throws and towels. Thread count only applies to woven bedding, and it is routinely inflated by counting each ply of a multi-ply yarn separately, so a "1000 TC" sheet is not necessarily better than a 300 TC one. Fibre quality and weave matter more than either number on its own.

Read the specification block, not the photograph — a styled image tells you nothing about scale. Look for the size stated in both cm and inches, and check whether a cushion listing is for the cover only or includes the insert; most Indian listings, including SOISU's, sell the cover alone. Then tape the stated size onto your floor or sofa and look at it. If a listing is unclear, ask before paying — SOISU answers on WhatsApp at +91 79779 59379 or decor@soisu.com, and will send a free QC photo of your exact unit on request. Size-mismatch is not a valid ground for return, so confirm first.
