DIY Weighted Blanket for Autism – Complete Tutorial
A comprehensive guide to creating a therapeutic sensory blanket
📊 Weight Calculator
The recommended weight is typically 10% of body weight plus 1-2 pounds.
📋 Materials Needed
💡 Fabric Selection Tips
Choose fabrics based on sensory preferences: smooth cotton for those who prefer less texture, or soft minky fabric for those who enjoy tactile input. Avoid fabrics that are too rough or have strong scents.
📐 Planning Your Blanket
Determine Size and Weight
Standard sizes:
- Child: 36″ x 48″ (3-5 lbs)
- Teen: 40″ x 60″ (5-8 lbs)
- Adult: 48″ x 72″ (8-15 lbs)
Create Weight Distribution Grid
Plan a grid of squares (typically 4″ x 4″ or 5″ x 5″) to ensure even weight distribution. Each square will hold an equal amount of filling.

✂️ Construction Steps
Prepare the Fabric
Cut your outer fabric pieces and one inner fabric piece to your desired dimensions. Pre-wash all fabrics to prevent shrinkage. Press with iron to remove wrinkles.
Create the Inner Pocket Layer
Using the inner fabric, mark your grid lines with a fabric marker. This will create individual pockets for the weighted filling. Use a quilting ruler for straight, even lines.
💡 Marking Tip
Use a water-soluble fabric marker that will wash out completely. Mark on the wrong side of the fabric when possible.
Sew the Grid Lines
Place the inner fabric between the two outer fabric pieces (right sides facing out). Sew along all your marked lines to create individual pockets. Start with vertical lines, then horizontal lines.
⚠️ Important
Use a strong, straight stitch and backstitch at the beginning and end of each seam. These seams will hold the weight, so they must be secure.
Fill the Pockets
Calculate how much filling goes in each pocket (total weight ÷ number of pockets). Use a small funnel or folded paper to add the precise amount to each pocket. Fill one row at a time, then sew that row closed before moving to the next.
Complete the Edges
After all pockets are filled and sewn closed, finish the outer edges with a strong seam. You can add binding tape for a professional finish or simply fold and hem the edges.
🧠 Autism-Specific Considerations
🎯 Sensory Preferences
Consider the individual’s sensory preferences when choosing materials. Some may prefer smooth textures, while others benefit from slightly textured fabrics. Avoid scratchy materials or strong chemical smells.
🌡️ Temperature Regulation
Choose breathable fabrics like cotton to prevent overheating. Some individuals with autism have difficulty regulating body temperature, so proper fabric choice is crucial.
🎨 Visual Considerations
Select colors and patterns based on the user’s preferences. Some may prefer calming solid colors, while others enjoy specific patterns. Avoid overly busy or high-contrast patterns that might be overstimulating.
⚠️ Supervision Guidelines
Always supervise initial use of the weighted blanket. Ensure the user can easily remove the blanket themselves and never use it during sleep without proper medical approval.
🔧 Maintenance and Care
Regular Inspection
Check seams regularly for wear or loose threads. Inspect pockets to ensure filling hasn’t shifted significantly or leaked.
Washing Instructions
Wash on gentle cycle with cold water. Air dry or use low heat setting. Due to the weight, you may need to use a commercial washer for larger blankets.

🧩 DIY Weighted Blanket FAQ
Expert answers to your most important questions about making weighted blankets for autism
⚠️ Important Safety Reminder
Always consult with an occupational therapist or healthcare provider before using a weighted blanket, especially for children with autism.
The general guideline is 10% of the user’s body weight plus 1-2 pounds. For example:
- 40-pound child: 5-6 pound blanket
- 60-pound child: 7-8 pound blanket
- 120-pound teen: 13-14 pound blanket
Yes, it can be safe when done correctly with proper materials and techniques. Key safety considerations:
- Use only poly pellets or glass beads – never rice, beans, or other organic materials
- Ensure all seams are double-stitched and reinforced
- Follow proper weight calculations
- Test the blanket thoroughly before use
Material choice depends on individual sensory preferences:
- Smooth cotton: Soft, breathable, easy to wash
- Bamboo fabric: Ultra-soft, temperature regulating
- Modal: Silky smooth, hypoallergenic
- Minky fabric: Soft, plush texture
- Fleece: Warm, cozy feeling
- Jersey knit: Stretchy, comfortable
Filling options: Poly pellets (quieter) or glass beads (smaller, more evenly distributed). Avoid plastic pellets that can be noisy.
Timeline varies based on experience and blanket size:
- Beginner sewers: 6-10 hours over 2-3 days
- Intermediate sewers: 4-6 hours in 1-2 sessions
- Experienced sewers: 3-4 hours in one day
Weighted blankets can be helpful for some individuals with autism, but results vary greatly:
- Deep pressure stimulation may promote calm feelings
- Can help with sleep regulation
- May reduce anxiety in some individuals
- Provides predictable sensory input
Size depends on the user’s age, bed size, and intended use:
- Lap blanket: 30″ x 40″ (for seated activities)
- Child blanket: 36″ x 48″ (ages 3-8)
- Teen blanket: 40″ x 60″ (ages 9-16)
- Adult blanket: 48″ x 72″ (adult use)
Consider: Smaller blankets are easier to handle and less overwhelming for first-time users. You can always make a larger one later if the smaller size is well-tolerated.
Proper care extends the life of your weighted blanket:
- Use cold water on gentle cycle
- Use mild detergent (avoid fabric softeners)
- For blankets over 15 lbs, consider commercial washers
- Air dry when possible, or low heat setting
Maintenance: Check seams monthly for wear, spot clean when possible, and consider making a removable cover for easier washing.
Not everyone with autism will enjoy weighted blankets, and that’s completely normal:
- Start with just 10-15 minutes of use
- Let them explore the blanket when calm, not during distress
- Try using it during preferred activities (watching TV, reading)
- Consider a lighter weight to start
DIY costs are typically much lower than buying pre-made blankets:
- Small blanket (5 lbs): $25-40
- Medium blanket (8 lbs): $35-55
- Large blanket (12+ lbs): $50-80
Cost breakdown: Fabric ($15-30), filling ($15-35), thread and supplies ($5-15). Compare to $100-300+ for commercial weighted blankets.
Yes, professional consultation is highly recommended, especially for children with autism.
- Determining if a weighted blanket is appropriate
- Calculating the right weight for the individual
- Identifying the best materials for sensory preferences
- Creating a safe introduction plan
- Monitoring effectiveness and safety
Many OTs who specialize in autism and sensory processing disorders can provide valuable guidance to ensure the blanket will be both safe and beneficial.
