Blanket Size Chart 2026: Complete Dimensions Twin to Cal King
Saatva Blankets & Throws
Saatva’s blanket lineup pairs GOTS-certified organic cotton and temperature-regulating fills with tailored sizing from throw to Cal King. 365-night trial, lifetime warranty, free white-glove delivery + old mattress removal.
- Throw blankets measure 50×60 in. Twin blankets run 60×80 to 66×90 in. Full/Queen range from 90×90 to 90×100 in.
- King blankets are 108×90 in. (standard) to 108×100 in. (deep-pocket version). Cal King typically measures 110×102 in. or larger.
- For full coverage, add 6 in. of hang on each side plus 6 in. tuck allowance beyond mattress edge.
- Comforters run 10–12 in. longer and wider than same-named blankets to achieve a draped silhouette.
- Saatva’s Spring 2026 sale reduces blanket prices up to 20%; top picks reviewed in section 4 below.
Blanket sizing is deceptively confusing. A “Queen blanket” from one brand may measure 90×90 in., while another labels the same dimensions “Full/Queen.” A Cal King buyer who grabs a standard King blanket (108×90 in.) ends up with a blanket that falls 2 inches short on each side. This guide cuts through inconsistent labeling with a complete, size-by-size reference table, plus guidance on how to measure your specific mattress setup for the right blanket fit.
If you only need throw sizing, the dedicated 50×60 blanket size guide covers throw-specific dimensions, fold configurations, and Saatva throw comparisons. This article covers the full spectrum from throw through Cal King.
1. Standard Blanket Sizes Chart
The table below reflects industry-standard dimensions used by major bedding brands in 2026. Because no single governing body enforces blanket sizing, you will see 1–3 inch variation between brands in the same category. The “typical range” column captures that variance.

| Size Name | Standard Dimensions | Typical Range | Best Fits |
|---|---|---|---|
| Throw | 50 × 60 in. | 48–54 × 58–62 in. | Sofa, accent decor, travel |
| Twin | 60 × 80 in. | 60–66 × 80–90 in. | Twin / Twin XL mattresses |
| Twin XL | 66 × 90 in. | 66–68 × 90–96 in. | Twin XL (college dorm standard) |
| Full / Double | 80 × 90 in. | 80–84 × 88–92 in. | Full / Double mattresses (54×75 in.) |
| Full / Queen | 90 × 90 in. | 88–92 × 88–92 in. | Full or standard Queen |
| Queen | 90 × 100 in. | 90–94 × 96–102 in. | Queen mattress (60×80 in.) deep pocket |
| King | 108 × 90 in. | 108–112 × 90–100 in. | King mattress (76×80 in.) |
| Cal King | 110 × 102 in. | 108–114 × 100–106 in. | California King mattress (72×84 in.) |
Key observation: A standard King blanket (108×90 in.) is wider than a Cal King blanket (110×102 in.) but shorter by 12 inches lengthwise. Cal King mattresses are 4 inches narrower and 4 inches longer than standard Kings, so using a King blanket on a Cal King bed leaves the foot uncovered. Always size up.

2. How to Measure Your Bed for Blanket Fit
The right blanket size depends on three variables: mattress surface dimensions, mattress depth, and how much hang or tuck you prefer. Most shoppers only check the first and end up with a blanket that exposes the box spring or does not stay tucked.
Step-by-step measurement formula
- Measure mattress width and length (top surface only, in inches).
- Add mattress depth × 2 to both width and length. Most modern mattresses run 10–14 in. deep; pillow-top or hybrid models often reach 15–18 in.
- Add 6 in. per side (12 in. total to width, 12 in. total to length) for a minimal drape appearance.
- Add 6 in. tuck allowance per side (12 in. total) if you tuck edges under the mattress for a hotel-style look. Hospital corners require an additional 6–8 in. foot tuck.
Worked example: Queen mattress, 12 in. deep, standard drape (no tuck)
| Dimension | Width | Length |
|---|---|---|
| Mattress surface | 60 in. | 80 in. |
| + depth drop (12 in. × 2) | +24 in. = 84 in. | +24 in. = 104 in. |
| + 6 in. hang each side | +12 in. = 96 in. | +12 in. = 116 in. |
| Minimum blanket size needed | 96 in. wide | 116 in. long |
At 96×116 in., a standard Queen blanket (90×100 in.) falls short on both axes. You would need a King or oversized Queen. This is why bedding brands selling “deep-pocket” or “oversized” blankets are not just marketing — they address real geometry for thicker mattresses.
Weighted blankets: Weighted blankets are sized to cover the sleeper, not drape the bed. They typically run 48×72 in. (twin-size sleeper) to 60×80 in. (full/queen sleeper), regardless of the mattress label. Sizing is personal weight-based, not bed-based. See the FAQ section below for the recommended weight formula.
3. Comforter vs. Blanket Sizes Explained
Blankets and comforters share the same size names but are not interchangeable on measurements. Comforters are designed with a 10–12 in. overhang per side to drape decoratively to the floor or at least below the mattress platform, whereas blankets are generally designed for surface coverage plus modest hang.
| Size | Typical Blanket | Typical Comforter | Width Difference |
|---|---|---|---|
| Twin | 60×80 in. | 68×90 in. | +8 in. wide / +10 in. long |
| Full / Queen | 90×90 in. | 92×96 in. | +2 in. wide / +6 in. long |
| Queen | 90×100 in. | 92×106 in. | +2 in. wide / +6 in. long |
| King | 108×90 in. | 104×98 in. | -4 in. wide / +8 in. long |
| Cal King | 110×102 in. | 108×98 in. | -2 in. wide / -4 in. long |
Notice that King comforters are often narrower than King blankets because comforter fills add loft that appears to cover more surface. When using a duvet cover, always verify insert dimensions match the cover dimensions rather than relying on the size label alone.
Duvet inserts: A down alternative duvet insert for a Queen bed typically measures 88×92 in. to 90×96 in. Saatva’s Down Alternative Comforter (Queen, $295) measures 90×96 in., falling within this range and sized for a modest, hotel-style drape rather than floor-length pooling.
4. Top 5 Saatva Blanket & Throw Picks by Size
Saatva’s bedding line uses GOTS-certified organic cotton and responsibly sourced fills. Current Spring 2026 pricing reflects discounts active through the sale period.
1. Saatva Organic Throw — 50×60 in. | $165
Woven from 100% GOTS-certified organic cotton in a 400-thread herringbone pattern. Weighs approximately 2.8 lbs — warm enough for four-season use on a sofa or as a bed layer without adding bulk. At 50×60 in., it covers one adult seated or two people sharing a narrow sofa. Available in four neutral colorways.
2. Saatva Down Alternative Comforter — Queen (90×96 in.) | $295
Box-stitch construction keeps the recycled polyester fill evenly distributed and prevents cold spots. Fill weight is 30 oz. (approximately 280 GSM equivalent), landing in the all-season range for most sleepers. OEKO-TEX Standard 100 certified shell. Works as a standalone layer on a Queen mattress or as a duvet insert inside a 90×96 in. cover.
3. Saatva Heritage Throw (Oversized) — 54×72 in. | $189
At 54×72 in., this oversized throw bridges the gap between a standard 50×60 in. throw and a Twin blanket. It covers a Twin mattress top surface (38×75 in.) without drapage, making it a useful transitional layer for guest beds or daybed styling. The heritage weave adds visual texture while the organic cotton shell remains breathable at 220 GSM (light summer weight).
4. Saatva Organic Cotton Blanket — King (108×90 in.) | $225
Waffle-weave organic cotton at 300 GSM delivers year-round warmth that is lighter than a down insert but heavier than a summer sheet. The King size (108×90 in.) covers a standard King mattress (76×80 in.) with a 16 in. drop per side and 5 in. drop at the foot — sufficient for modest drape without tucking. Upgrade to the deep King (108×100 in.) if your mattress exceeds 14 in. in depth.
5. Saatva Organic Cotton Blanket — Cal King (110×102 in.) | $245
The Cal King variant of the same waffle-weave blanket adds 2 in. of width and 12 in. of length versus the standard King, correctly addressing the Cal King mattress’s narrower-but-longer geometry (72×84 in.). The 110 in. width provides a 19 in. side drop; the 102 in. length offers an 18 in. foot and head drop combined on a 14 in. deep mattress with 6 in. surface coverage. Same GOTS-certified organic cotton, 300 GSM.
5. Material & Warmth Selection by GSM
Grams per square meter (GSM) measures fabric weight and is a reliable proxy for thermal warmth in flat-woven blankets. The relationship is approximately linear: double the GSM, roughly double the insulation at equivalent fiber content.
| GSM Range | Classification | Best Season | Typical Use |
|---|---|---|---|
| 150–200 GSM | Lightweight | Summer / AC rooms | Cotton percale, gauze, muslin blankets |
| 200–250 GSM | Summer weight | Spring / Summer | Breathable cotton, bamboo blends |
| 300–400 GSM | All-season | Year-round | Waffle weave, French terry, wool-cotton blend |
| 500–600 GSM | Heavyweight | Fall / Winter | Merino wool, sherpa-lined, fleece |
| 600+ GSM | Ultra-heavyweight | Winter only | Cable-knit wool, heavy sherpa double-layer |
Fiber comparison by size category
Throw blankets (50×60 in.): Decorative throws tolerate heavier GSM (400–600) because they are folded or draped rather than lying flat. A 600 GSM wool throw at 50×60 in. weighs roughly 4.5–5 lbs — manageable to fold and toss over a sofa arm.
Queen/King flat blankets (90–108 in. wide): At full-bed scale, every 100 GSM adds approximately 0.8–1.2 lbs of total weight depending on dimensions. A King blanket at 500 GSM (108×90 in.) weighs about 7–9 lbs, which affects how smoothly it can be tucked and whether it shifts during sleep. Weighted blankets start at 10–15 lbs by design; standard blankets above 600 GSM in King can approach that range unintentionally.
Down and down-alternative: Fill power (FP) replaces GSM as the warmth metric for lofted fills. 600 FP is suitable for year-round use in most climates; 700–800 FP is appropriate for cold sleepers or unheated bedrooms. Down-alternative polyester fill weight in ounces (oz.) correlates roughly as: 20–25 oz. = summer; 28–35 oz. = all-season; 40+ oz. = winter.
6. Care & Machine Wash by Blanket Size
Washing a King-size blanket in an undersized machine causes uneven cleaning, excessive wear on seams, and potential motor strain. The following drum capacity guidelines apply to top-load and front-load washers.
| Blanket Size | Dry Weight (approx.) | Min. Washer Capacity | Notes |
|---|---|---|---|
| Throw (50×60 in.) | 2–4 lbs | 2.5 cu. ft. | Standard home washer sufficient |
| Twin (60×80 in.) | 3–5 lbs | 3.5 cu. ft. | Most household washers handle without issue |
| Full / Queen (90×90 in.) | 4–7 lbs | 4.5 cu. ft. | Wash alone, no other items in load |
| Queen (90×100 in.) | 5–8 lbs | 4.5–5.0 cu. ft. | Front-load preferred for even water distribution |
| King (108×90 in.) | 6–10 lbs | 5.5 cu. ft. | Laundromat commercial washer if home unit is under 5.5 cu. ft. |
| Cal King (110×102 in.) | 7–12 lbs | 5.5–6.0 cu. ft. | Commercial washer strongly recommended for wool or sherpa fills |
Care by fabric type
100% cotton (including organic): Machine wash cold on a gentle cycle. Tumble dry low. Avoid hot water, which causes cotton to shrink 3–5% in the first wash. For a King blanket, 5% shrinkage on 108 in. width means losing 5.4 in. per dimension. Pre-wash before first use if shrinkage matters.
Wool and wool blends: Wool requires a wool-specific cycle (spin speed 600 RPM or less) and a wool-safe detergent (pH-neutral, sulfate-free). Never tumble dry wool at heat. Lay flat or hang to dry. Weighted wool blankets above 8 lbs are best dry-cleaned.
Down and down-alternative comforters: Use a large-capacity front-load washer (minimum 5.0 cu. ft. for Queen, 6.0 cu. ft. for King). Add two clean tennis balls or wool dryer balls to the dryer to prevent fill clumping. Dry on low for 2–3 cycles until completely dry — any residual moisture creates mildew in the baffles.
Saatva-specific care: Saatva’s organic cotton blankets and throws carry a machine-wash-cold / tumble-dry-low care code. The manufacturer recommends washing before first use. For Saatva’s Down Alternative Comforter, use a commercial washer or laundromat for the King and Cal King sizes to ensure the full perimeter receives adequate agitation and rinse.

8. FAQ: 6 Common Blanket Sizing Questions
What is the difference between an oversized King and a standard King blanket?
A standard King blanket measures 108×90 in. An oversized King (also called deep King or King plus) typically measures 108×100 in. or 112×100 in., adding 10 extra inches of length to accommodate mattresses 14–18 in. deep without exposing the box spring. If your King mattress is thicker than 12 in., the oversized King is the correct choice for full coverage without tucking.
How many extra inches do I need for hospital corner tucks on a King bed?
Hospital corners require a minimum of 10–12 in. of fabric beyond the mattress edge at the foot and sides. On a King mattress (76×80 in., 12 in. deep), the minimum blanket dimensions for proper hospital corners are approximately 112×110 in. — meaning a standard King blanket (108×90 in.) falls short on length by 20 in. An oversized King (112×100 in.) gets closer but still requires a low-profile bed frame and shallow mattress depth to achieve clean hospital corners. Most hospitality properties use a top sheet as the tucked layer and a blanket as a separate untucked layer on top.
Can I use a dust ruffle with a King blanket, and does blanket size affect this?
Dust ruffles (bed skirts) sit between the mattress and box spring and are independent of blanket sizing. However, blanket drop length determines how much of the dust ruffle is visible. A King blanket (108×90 in.) on a 12 in. deep mattress provides roughly 5 in. of drop below the mattress bottom, which may partially obscure a 14 in. dust ruffle but will not fully cover it. If you want the blanket to hide the ruffle entirely, add the full mattress-to-floor distance (typically 22–26 in. including box spring height) to the mattress surface length when calculating required blanket dimensions.
How do I choose the right weighted blanket size?
Weighted blanket sizing follows body weight, not bed size. The standard recommendation is 10% of body weight plus 1–2 lbs. For a 150 lb adult, that is 16–17 lbs. Dimension-wise, weighted blankets are sized to cover the sleeper body from shoulders to feet rather than drape the mattress: 48×72 in. for a single adult up to 5 feet 8 inches (Twin equivalent), 60×80 in. for taller adults or couples sharing (Queen equivalent). Using a weighted blanket sized for the full bed rather than the sleeper wastes fill weight on fabric that hangs off the edges where no one is lying, reducing the effective pressure stimulus.
What blanket size is best for children and toddlers?
For children 12 months and older transitioning to a toddler bed (typically 27×52 in.), a blanket of 42×58 in. provides adequate coverage without excess fabric. For a Twin bed (38×75 in.), a standard Twin blanket (60×80 in.) is appropriate. The American Academy of Pediatrics recommends no loose bedding in cribs for infants under 12 months. Saatva’s Youth mattress (Twin size, dual-sided for ages 3–12) pairs well with a 60×80 in. Twin blanket at that stage.
Do blankets fade in the wash, and does blanket size affect this?
Color fading is primarily a function of dye quality, wash temperature, and detergent chemistry, not blanket size. However, size affects fade indirectly: larger blankets (King, Cal King) that are washed in undersized machines get bunched against the drum, creating uneven agitation and mechanical friction that abrades fiber dye bonds faster. Front-load washers with adequate capacity allow the blanket to move freely, reducing both fading and fiber pilling. To preserve color: wash cold, use a color-safe detergent, turn the blanket inside out if it has a printed or embossed pattern, and dry on low or air-dry.
Verdict & Final Recommendation
For most sleepers, the right blanket size is one size up from what the bed label suggests, especially if the mattress exceeds 12 in. in depth. Queen sleepers with modern hybrids (13–15 in.) should consider the deep Queen or King option. Cal King owners should never substitute a standard King blanket: the geometry does not align.
Among the options on the market in 2026, Saatva’s organic cotton blanket line stands out for three reasons: GOTS-certified materials, consistent size execution that matches stated dimensions within 1 in., and a 365-night return window that reduces the risk of sizing mismatches. The Spring 2026 sale currently reduces bedding prices, making this a reasonable time to purchase.
If you primarily need a throw for sofa or accent use, the dedicated 50×60 throw size guide covers format-specific recommendations and fold configurations in greater depth.
