Thread Count to GSM Converter কি?

The Thread Count to GSM Converter estimates fabric weight (GSM = grams per square meter) from bedsheet thread count and fabric type. GSM is the more accurate quality metric than thread count alone — it measures actual fabric density and weight. Higher GSM (within fabric type) means denser, more durable, often warmer sheets. The calculator accounts for yarn ply (single, 2-ply, multi-ply) since marketing-inflated thread counts often use multi-ply yarns to claim higher numbers without proportional quality improvement.

GSM ≈ Fabric Base Weight + (Thread Count × Fabric Multiplier × Ply Adjustment)
TC
Thread Count (threads/sq inch) — Horizontal + vertical threads per square inch
GSM
Grams per Square Meter (g/m²) — International fabric weight standard

  2. 2Select fabric type (percale, sateen, flannel, linen, bamboo, etc.)
  3. 3Select yarn ply: single-ply (legitimate quality), 2-ply (twisted), multi-ply (marketing)
  4. 4Calculator estimates GSM and quality category
  5. 5Quality categories: lightweight (<100), standard (<150), premium (<200), luxury (<280), heavy (>280)
  6. 6Thread count assessment flags suspicious counts above 800 as likely multi-ply inflation

সমাধান করা উদাহরণ

ইনপুট
400 thread count cotton percale, single-ply
ফলাফল
152 GSM premium quality — sweet spot for most uses
ইনপুট
1000 thread count multi-ply
ফলাফল
~150 GSM effective; 500-effective single-ply equivalent
ইনপুট
300 thread count linen
ফলাফল
176 GSM — perfect summer weight

এড়ানোর সাধারণ ভুল

  • Treating thread count as universal quality metric — above 600 it's often marketing inflation
  • Comparing percale to sateen on thread count alone — completely different fabric structures
  • Ignoring yarn ply — 1000-count 2-ply sheets often inferior to 400-count single-ply
  • Assuming higher GSM = better — too heavy for hot sleepers, too thin for winter use

সচরাচর জিজ্ঞাসা

What's the ideal thread count for sheets?

300-500 single-ply is the sweet spot for most uses. Below 200 feels thin. Above 800 typically indicates multi-ply marketing inflation. Quality matters more than count — Egyptian cotton 300-count beats poor-quality cotton 1000-count.

What is GSM and why does it matter?

GSM (grams per square meter) measures actual fabric weight regardless of thread count manipulation. More direct quality measure. Light bedding 90-180 GSM, medium 180-240, heavy 240-300+. Linen typically 140-200 GSM, cotton percale 90-140, sateen 110-160.

What's the difference between percale and sateen?

Percale: one-over-one-under plain weave. Crisp, cool, breathable, matte finish. Better for hot climates and warm sleepers. Sateen: four-over-one-under weave. Silky, smooth, slightly warmer, sheen finish. Better for cool climates and luxe feel preference.
