How to Choose a Picnic Blanket
A good picnic blanket can make spending time outdoors much more comfortable. Whether you're enjoying lunch in the countryside, visiting the beach, relaxing in a park or taking the family camping, a suitable blanket provides somewhere to sit, eat and take a break.
However, not all picnic blankets are the same. Some are designed to be lightweight and compact, while others prioritise comfort, insulation or protection from damp ground.
Choosing the right picnic blanket involves considering where you'll use it, how many people need to sit on it and how much space it will take up when packed away.
In this guide, we'll explain the different types of picnic blankets, what materials to look for and which features are most useful for outdoor activities.
What Is a Picnic Blanket?
A picnic blanket is a portable ground covering designed to provide a more comfortable surface for sitting, eating or relaxing outdoors.
Unlike an ordinary household blanket, many picnic blankets are made with outdoor use in mind.
Depending on the design, they may include:
- Water-resistant or waterproof backing.
- A comfortable upper surface.
- Insulating layers.
- Durable outdoor fabrics.
- Foldable construction.
- Integrated carrying handles or straps.
- Easy-clean materials.
Not every picnic blanket includes all these features, so it's worth considering which are most important for your intended use.
Different Types of Picnic Blankets
Picnic blankets are available in several designs, each offering different advantages.
Traditional Fabric Picnic Blankets
Traditional picnic blankets are often made from woven fabrics, fleece or other soft materials.
They can provide a comfortable surface for sitting on dry grass or other suitable ground.
Advantages:
- Often soft and comfortable.
- Available in various sizes.
- Can be suitable for relaxed outdoor use.
- Some designs can double as ordinary blankets.
Considerations:
- May absorb moisture from damp ground.
- Can become heavy when wet.
- Some materials collect grass, sand or debris.
These blankets are generally most suitable when the ground is dry or when moisture protection isn't a priority.
Waterproof-Backed Picnic Blankets
Waterproof-backed picnic blankets incorporate a protective underside intended to reduce moisture passing through from the ground.
They can be particularly useful in the UK, where grass may remain damp even when the weather is dry.
Advantages:
- Help protect against moisture from damp ground.
- Often easier to wipe clean underneath.
- Useful for parks, countryside visits and family outings.
- Can provide a practical barrier between clothing and the ground.
Considerations:
- Waterproof performance depends on the backing material and construction.
- Some designs may be heavier than simple fabric blankets.
- The upper surface may still absorb rain or spills.
A waterproof backing doesn't necessarily mean the entire blanket is waterproof.
Padded and Insulated Picnic Blankets
Some picnic blankets include a padded or insulating layer between the upper fabric and backing.
This can improve comfort when sitting on firm or slightly uneven surfaces.
Advantages:
- Can provide additional cushioning.
- May reduce heat loss to colder ground.
- Useful for longer periods of sitting.
- Often comfortable for family picnics.
Considerations:
- May be bulkier when folded.
- Can take longer to dry if the upper fabric becomes wet.
- May weigh more than lightweight alternatives.
Padding is useful for comfort, but it shouldn't be confused with the level of insulation provided by a purpose-designed sleeping mat.
Lightweight Packable Picnic Blankets
Lightweight picnic blankets prioritise portability and compact packed size.
They may be made from thin synthetic fabrics and can be useful when walking or travelling with limited space.
Advantages:
- Often lightweight.
- Easy to carry in a rucksack.
- Can pack into a small space.
- Useful for spontaneous stops and short breaks.
Considerations:
- May provide limited cushioning.
- Thin fabrics can offer less protection from rough ground.
- Some designs may move in windy conditions.
Picnic Blanket Types Compared
| Blanket Type | Main Advantage | Best Suited To |
|---|---|---|
| Traditional fabric | Softness and comfort | Dry parks and relaxed picnics |
| Waterproof-backed | Protection from damp ground | Grass, countryside and family outings |
| Padded or insulated | Additional comfort | Longer picnics and cooler surfaces |
| Lightweight packable | Portability | Walking, travel and short stops |
Many picnic blankets combine features from more than one category. For example, a blanket may have a soft upper surface, padded middle layer and waterproof backing.
What Size Picnic Blanket Do You Need?
The right size depends on how many people will use the blanket and whether you need space for food, bags or other belongings.
A blanket that is too small can feel cramped, while an unnecessarily large one may be awkward to carry.
Small Picnic Blankets
Smaller blankets may be suitable for one or two people taking a short break outdoors.
They can also be useful when packed size and weight are important.
Medium Picnic Blankets
Medium-sized blankets can provide space for a couple of adults or a small family, depending on their dimensions and how everyone sits.
They may offer a practical compromise between comfort and portability.
Large Family Picnic Blankets
Larger blankets are useful when several people need to sit together or when you want space for food and belongings.
They may be particularly convenient for family picnics, outdoor events and days at the beach.
Picnic Blanket Size Guide
The following dimensions are approximate examples rather than fixed industry standards.
| Blanket Dimensions | Approximate Area | Possible Use |
|---|---|---|
| 100 × 150 cm | 1.5 m² | One or two people sitting closely |
| 150 × 150 cm | 2.25 m² | Small picnics or short breaks |
| 150 × 200 cm | 3 m² | Family picnics with some extra space |
| 200 × 200 cm | 4 m² | Larger family gatherings |
Remember that the number of people who can sit comfortably on a blanket depends on their size, seating position and the amount of equipment placed on it.
Is a Waterproof Picnic Blanket Worth It?
For regular outdoor use in Britain, a waterproof-backed picnic blanket can be particularly practical.
Grass often remains damp after overnight rain, morning dew or periods of humid weather.
Even on a sunny afternoon, moisture can transfer through an ordinary fabric blanket.
A suitable waterproof backing helps create a barrier between the ground and the upper surface.
However, it's important to understand the difference between waterproof and water-resistant materials.
Water-Resistant Backing
Water-resistant materials can repel some moisture but may allow water through under prolonged contact or pressure.
Waterproof Backing
Waterproof materials are designed to prevent water passing through under specified conditions.
Actual performance depends on the material, construction, seams and condition of the blanket.
Always check the manufacturer's description rather than assuming that every outdoor picnic blanket is fully waterproof.
Which Picnic Blanket Material Is Best?
Different materials offer different benefits for comfort, durability and ease of cleaning.
Fleece
Fleece is commonly used for soft upper surfaces.
It can feel comfortable against clothing and skin, although some fleece fabrics may collect grass, sand and other debris.
Polyester
Polyester is widely used in outdoor textiles because it can be lightweight, durable and relatively easy to maintain.
Its performance depends on the fabric construction and any additional coatings.
Nylon
Nylon can offer good strength relative to its weight and is often used in lightweight outdoor equipment.
Thin nylon blankets may prioritise packability over cushioning.
Waterproof-Coated Fabrics
Some blankets use coated fabrics or separate waterproof backing layers.
These can help reduce moisture transfer from damp ground.
Coatings and backing materials vary, so check the product's care instructions and intended use.
How Important Is Picnic Blanket Thickness?
Thickness affects both comfort and portability.
A thin blanket may be easy to carry but provide little cushioning against stones, roots or uneven ground.
A thicker padded blanket can feel more comfortable but may take up considerably more space.
Think about where you normally sit.
- Soft grass: A lightweight blanket may provide enough comfort.
- Firm ground: Some padding may be beneficial.
- Cool surfaces: An insulating layer may improve comfort.
- Rocky or uneven areas: Choose a suitable seating location rather than relying entirely on blanket thickness.
For extended camping use, a purpose-designed sleeping mat is generally more appropriate than a picnic blanket.
See our Sleeping Mat Buying Guide for more information.
How Small Should a Picnic Blanket Pack?
Packed size becomes particularly important when carrying a blanket on a walk or travelling with children.
Some blankets fold into a compact pouch, while others roll or fold into a larger bundle.
Consider:
- How much room you have in your bag.
- Whether you'll carry the blanket by hand.
- How easy it is to fold after use.
- Whether the carrying straps are secure.
- Whether the packed blanket is manageable for your intended activity.
For walking and hiking, lightweight compact designs are generally more convenient than bulky padded blankets.
Should You Choose a Picnic Blanket with a Carry Handle?
Integrated handles or carrying straps can make a picnic blanket easier to transport.
They can be especially useful when carrying food, drinks and children's belongings at the same time.
Look for secure fastenings and a folding system that is straightforward to use.
If the blanket will usually travel inside a rucksack, an integrated handle may be less important.
What Is the Best Picnic Blanket for Families?
For family outings, a picnic blanket should ideally balance comfort, practical size and ease of cleaning.
Useful features may include:
- Enough space for everyone to sit comfortably.
- A water-resistant or waterproof underside.
- A comfortable upper surface.
- Durable materials.
- Easy folding and carrying.
- Simple cleaning after food spills or muddy shoes.
Families with younger children may particularly appreciate a blanket that can be wiped or cleaned easily.

What Is the Best Picnic Blanket for the Beach?
Beach use presents slightly different challenges from sitting on grass.
Sand can collect in textured fabrics, while wind may cause lightweight blankets to move.
When choosing a blanket for the beach, consider:
- Whether sand can be shaken off easily.
- How quickly the material dries.
- Whether the blanket is easy to clean.
- Its packed size.
- Whether the design offers suitable ways to keep it in position.
Some lightweight beach blankets include corner pockets or attachment points intended to help secure them.
Only use suitable fixing methods and avoid creating trip hazards.
Remember that a picnic blanket doesn't provide protection from the sun. Suitable shade, clothing and other sun precautions may still be necessary.
Read our sun safety guide for more information.
What Is the Best Picnic Blanket for Camping?
A picnic blanket can be a useful addition to family camping equipment.
It can provide somewhere to sit outside the tent, eat lunch or relax during the day.
For camping, consider:
- Durable construction.
- Protection against damp ground.
- Ease of cleaning.
- Comfort on firm surfaces.
- Suitable packed size.
A picnic blanket is not a replacement for a suitable sleeping mat or tent groundsheet.
Each piece of equipment serves a different purpose.
Can You Use a Picnic Blanket for Outdoor Events?
Picnic blankets are useful for outdoor concerts, sporting events, festivals and other gatherings where sitting on the ground is permitted.
For these activities, a compact design with a carrying handle may be particularly convenient.
Check event rules before attending, as some venues restrict the size or type of equipment that visitors can bring.
How to Keep a Picnic Blanket Clean
Regular cleaning can help keep your picnic blanket comfortable and in good condition.
The correct method depends on its materials and construction.
After Each Use
- Shake off loose grass, sand and dirt.
- Remove any food crumbs or debris.
- Wipe away suitable surface marks.
- Check whether the blanket is damp.
- Allow it to dry thoroughly before long-term storage.
Washing a Picnic Blanket
Some fabric picnic blankets may be machine washable, while others require hand cleaning or wiping with a damp cloth.
Always follow the manufacturer's care instructions.
Do not assume that a blanket with waterproof backing can be machine washed, tumble dried or ironed.
Excessive heat or unsuitable detergents may damage coatings or laminated materials.
How to Store a Picnic Blanket
Before storing your picnic blanket, make sure it is clean and completely dry.
Leaving a damp blanket folded for long periods can encourage unpleasant odours and potentially mould or mildew.
Store it in a cool, dry location away from unnecessary heat and prolonged direct sunlight.
If the blanket has a waterproof coating, follow any specific storage recommendations provided by the manufacturer.
How Long Should a Picnic Blanket Last?
The lifespan of a picnic blanket depends on its materials, construction, frequency of use and care.
A well-maintained blanket may provide many seasons of use.
Check periodically for:
- Worn or damaged fabric.
- Loose stitching.
- Damaged waterproof backing.
- Broken straps or handles.
- Persistent odours or deterioration.
If the waterproof backing becomes damaged, the blanket may no longer provide its original level of moisture protection.
Common Mistakes When Choosing a Picnic Blanket
Choosing a Blanket That's Too Small
Remember to allow space for food, drinks and belongings as well as people.
Ignoring Ground Moisture
An ordinary fabric blanket may become damp when placed on wet grass.
Prioritising Thickness Over Portability
A thick blanket may be comfortable but inconvenient to carry on longer walks.
Assuming Every Blanket Is Waterproof
Some blankets only provide limited water resistance, while others have waterproof backing but absorbent upper surfaces.
Overlooking Cleaning Requirements
Materials that collect dirt or require complicated cleaning may be less convenient for frequent family use.
Buying Without Checking Packed Dimensions
A large family blanket may take up more space than expected when folded.
