How many kg is a curtain?

Curtains come in a wide variety of sizes, materials, and weights. Determining the kilograms (kg) of a specific curtain depends on several factors:

How many kg is a curtain?

Curtain Size

The dimensions of the curtain affect its overall weight. Some key measurements include:

  • Width – Typical widths range from 50 cm for café curtains up to 300 cm for wide living room curtains. Wider curtains require more fabric.
  • Length – Lengths range from sill length (~60 cm) to floor length (250+ cm). Longer curtains have more material.
  • Number of Panels – More curtain panels mean more total fabric weight.

Curtain Materials

The type of fabric greatly impacts the weight. Common materials include:

  • Cotton – Lightweight and breathable, weighs approximately 290 grams per square meter.
  • Linen – Natural fiber with textured look, medium weight about 400 gsm.
  • Velvet – Made with dense piled fabric, quite heavy at ~620 gsm.
  • Sheers/Voile – Light, semi-transparent fabrics around 50 gsm.

Heavier brocade, tapestry, blackout fabrics, and those with trims, lining, or interlining will weigh more than plain weave cotton or linen fabrics.

Breakdown by Curtain Type

Below are weight estimates for some typical curtain sizes and materials:

  • Small café curtains (50×60 cm) in lightweight cotton = ~250 grams.
  • Living room curtains (240×245 cm) in medium weight linen = ~2.5 kg each panel. For a total of 3 panels that’s ~7.5 kg.
  • Long velvet drapes (300×275 cm) = ~8.3 kg per panel. So a pair would be ~16.6 kg.
  • Sheer single panel (80×245 cm) in gauze = ~200 grams.

To determine the weight precisely, check the packaging label or contact the manufacturer. Custom made curtains may include that info with the order.

Factors that Increase Curtain Weight

Some additional curtain elements that boost the overall kilograms include:

  • Lining – Lined curtains can weigh 2-3x more than unlined.
  • Layers – Sheers, scarf swags and under treatments add layers and weight.
  • Hardware – Rods, hooks, holdbacks and carriers should be counted too.
  • Embellishments – Trims, tassels, embroidery and beading are extra.

Tips for Measuring Curtains

Follow these steps for weighing existing curtains:

  • Use a clothing scale, fish scale, or shipping scale for accuracy.
  • Weigh sections separately if too bulky, then add up.
  • Subtract hardware if possible for just the fabric weight.
  • Write down the measurements including sizes for reference.
  • Contact the manufacturer if the packaging is available.

Knowing the weight in kilograms helps for cleaning, shipping and calculating costs for custom curtains. When planning new curtains, use the fabric weight charts and typical sizes as a guideline for number of kilograms expected.

Key Takeaway

The weight of curtains spans a large range depending on exact dimensions and fabric density, however typical numbers are:

  • Small café curtains = ~0.25 kg
  • Living room panel = ~2.5 kg
  • Long velvet drapes = ~8 kg per panel
  • Sheer single panel = ~0.2 kg

With lining, embellishments and more panels, the total kilograms add up quickly. Measuring precisely provides the real curtain weight.


In summary, common curtain fabrics vary greatly in grams per square meter, resulting in small sheers weighing around 0.2 kg up to heavy velvet drapes weighing 8+ kg each. To find the total kilograms for custom curtains, identify the number of panels based on window measurements, choose a fabric type and check the estimated weight per meter or yard. Calculate the total square area covered, multiply by fabric density, add any linings or embellishments, and convert to kg. This provides the approximate customized curtain order weight. For existing curtains, use a scale and follow measurement best practices to determine current curtain weights in kilograms. Consider all components and check manufacturer info for the most accurate curtain weights.

Frequently Asked Questions

  1. How do you calculate the weight of curtains?
    To calculate curtain weight, multiply the total fabric area (width x length of each panel) by the fabric weight per square meter or yard. Add weights for any additional lining, layers, embellishments or hardware. Convert the total gram weight to kilograms.

  2. How heavy should curtains be?
    Ideal curtain weight depends on several factors: window size/exposure, privacy needs, hardware capacity and look/drape desired. Light, medium and heavy density fabrics range in weight from ~50 gsm to over 600 gsm. Choose weight to balance aesthetics, function and ease of handling.

  3. How much fabric do I need for curtains?
    Measure window height and width, allowing extra for optimal fullness and drape. Calculate the total area x number of panels + overlap. Add 15-30% extra fabric for shrinkage, pattern matching and errors to determine total yardage/meters needed. Order swatches first to estimate prepared fabric weight.

  4. Can curtains be too heavy?
    Overly heavy curtains can be difficult to operate, cause excessive wear/sagging of rods and hardware over time or even fall due to inadequate support. Check hardware weight limits and installer recommendations, using appropriate anchors, brackets and components for large/heavy drapes.

  5. What is the most cost effective curtain?
    Basic styles in affordable, medium-weight fabrics like polyester blends or 100% cotton offer durability and moderate pricing. Add enhancements like lining, tie-backs and trim after establishing the budget, measurements, style and essential components first.

  6. What fabric is opaque but still light enough for curtains?
    Polyester or poly/cotton blends around 200 gsm offer opacity for privacy while still allowing some light through. Light-filtering linen or heavier weave cotton work well too. Or pair an opaque lining with a sheer outer layer for the illusion of light, airy curtains with full coverage.

  7. How do I calculate fabric yardage for curtains?
    Make rough yardage estimates by multiplying finished length x width for each panel, adding 15-30% extra. Or use the precise formula: Height x Width x Number of Panels x (1.3 or 1.5) divided by 36. Allow more for pattern matching or longer drapes.

  8. How wide should curtain panels be?
    For proper light blocking and stack-back, panels should be about 2x the width of the window. But also consider room size and existing hardware. Average panel widths are 50-120 cm. Extra wide 300+ cm panels suit some large spaces but can be very heavy.

  9. What is the most cost-effective curtain rod?
    Sturdy yet affordable option are 1-inch diameter steel rods with decorative finials. Increase holding capacity with heavier, double rods or stronger metals like aluminum or iron if planning very wide/long panels. Try to match hardware metal finishes for a cohesive look.

  10. Which curtain lining blocks the most light?
    For maximum light blockage, use white or light colored blackout lining on backside of curtains facing window. White reflects more sunlight outward while still allowing softer indoor light through top layers. Thermal/insulated fabrics also help reduce solar heat/glare.

  11. How do I calculate the price per meter of a curtain fabric?
    If the total cost and exact yardage or meterage of the fabric length is listed, divide the full price by the total linear meters to get price per meter. This allows comparison shopping. If meters or yardage is unknown, inquire or estimate based on average widths.

  12. How do I measure for custom made curtains?
    Start by carefully measuring the exact window height and width. For floor length deduct space needed above window frame for mounting. Determine desired overlay width and length. Measure any obstacles like handles/cranks. Add at least 5 cm for hems and shrinkage. Supply all measurements, details and fabric selection to curtain maker.

  13. Do blackout curtains have to be heavy?
    No, some specially engineered lighter weight blackout fabrics can still fully block external light effectively. Or pair sheer, light panels with separate blackout linings rather than one very heavy blackout layer. Proper installation covering hardware and edges also helps reduce light leaks.

  14. What thickness of fabric is best for curtains?
    Light filtering curtains around 200-300 gsm deliver an airy, billowing look while still providing UV protection and some privacy. For room darkening 400-500 gsm is ideal. Go even thicker for superior insulation, sound dampening or a lush, dramatic profile.

  15. How do I calculate how many spools I need for curtain tiebacks?
    First count the number of curtains that need tiebacks, if doing one spool per panel. Then check spool yardage and calculate total linear yards needed. Divide total yards by yards per spool for the number of spools to purchase. Add a couple extra since cutting lengths often leaves unused remnants per spool.

  16. Is polyester or cotton better for curtains?
    Both fabrics have pros and cons. Polyester resists shrinking, staining and fading better long-term. But natural fibers like cotton breathe better and offer a cozier look. Blends optimize positives of each! Check cleaning requirements when choosing.

  17. How do you measure curtains without taking them down?
    Use an adjustable curtain gauge tool set to the width of the rod, then place on each end to measure overall width. For length, use a household tape measure placed at top corner edges and run down the front to hem, deducting height of rod/hardware.

  18. Do I really need to pay for curtain lining?
    Lining boosts overall weight, provides extra insulation for sound/temperature, and improves drape. But it also adds cost. For budget styles or casual spaces like kids rooms, skip the lining without sacrificing function. Just check opacity of main fabric first.

  19. Do curtains shrink when you wash them?
    Pre-wash fabric before hemming for maximum shrinkage, especially for natural fibers like cotton/linen. Even with preshrinking, additional subtle shrinkage will occur with cleaning over time. When calculating measurements leave at least 5 extra cm just in case.

  20. How do I find the Grams per Square Meter of a fabric?
    Check manufacturer details for the most reliable metric. If unknown, weigh a 1-meter square piece of fabric. Convert the gram weight to GSM. Different weave densities, yarn types and finishing processes affect the GSM even for similar fabric varieties.
