How to Choose the Right Thickness for Your Picnic Mat: A Comprehensive Guide
Created on 09.09
There’s nothing quite like spreading out a picnic mat under the sun, sharing snacks with loved ones, or enjoying a quiet moment with a book. But if your mat is too thin, you might end up feeling every rock, twig, or bump in the grass. Too thick, and it becomes bulky to carry, defeating the purpose of a portable outdoor essential. The key to a comfortable picnic lies in choosing the right thickness—and it’s not a one-size-fits-all decision. In this guide, we’ll break down everything you need to know to pick a picnic mat thickness that balances comfort, portability, and practicality.
Why Does Picnic Mat Thickness Matter?
Before diving into specific measurements, let’s first understand why thickness is such a critical factor. A picnic mat’s primary job is to:
- Insulate you from cold, damp ground (especially early in the morning or during fall/winter outings).
- Cushion against hard surfaces, rocks, or uneven terrain.
- Protect your food, blankets, and belongings from dirt, moisture, or bugs.
The wrong thickness can compromise all three. A 2mm mat might be easy to roll up, but it won’t shield you from a dewy lawn or a sharp pebble. A 15mm mat, while luxuriously soft, could weigh 3+ pounds and take up half your backpack. The goal is to match the thickness to your specific use case—and we’re here to help you do just that.
Key Factors to Consider Before Choosing Thickness
Your ideal picnic mat thickness depends on four main factors. Answer these questions first, and you’ll narrow down your options in no time:
1. Where Will You Use the Mat?
The terrain and environment are the biggest drivers of thickness needs:
- Grass or soft soil (parks, backyards): These surfaces are relatively forgiving, so you can opt for a thinner mat.
- Rocky ground, gravel, or concrete (hiking trails, urban plazas): You’ll need extra cushioning to avoid discomfort.
- Damp or wet areas (lakesides, coastal parks, spring outings): Thicker mats often have better water resistance and insulation against cold, wet ground.
2. Who Will Be Using It?
Comfort preferences vary by age and mobility:
- Adults only: If you’re packing light for a quick picnic, a thinner mat may suffice.
- Kids or toddlers: They’ll be crawling, rolling, and playing—so a thicker, softer mat is a must to prevent bumps and scrapes.
- Elderly or those with joint pain: Extra cushioning reduces pressure on knees and hips when sitting or getting up.
3. How Will You Carry It?
Portability is a trade-off with thickness:
- Backpacking or biking to the picnic: Stick to thin, lightweight mats (2–5mm) that roll up small.
- Driving to a nearby park: You can splurge on a thicker, more comfortable mat (8–15mm) since you won’t have to carry it far.
- Camping trips (picnics + overnight use): Look for 5–10mm mats that balance cushioning and packability.
4. How Long Will You Stay?
A 30-minute snack break vs. a 3-hour afternoon picnic calls for different thicknesses:
- Short outings: Thin mats are practical—you won’t notice minor discomfort for a quick visit.
- Long stays: Thicker mats prevent “ground fatigue” and keep you cozy for hours.
Picnic Mat Thickness Guide: Common Sizes & Their Best Uses
Now that you’ve considered your needs, let’s map them to standard picnic mat thicknesses. Most mats range from 2mm to 15mm, with each size serving a distinct purpose.
1. Thin Mats (2–5mm): The Portable Workhorses
Best for: Day trips, backpacking, biking, short picnics in grassy parks, or solo outings.
Materials: Often made of lightweight polyester, nylon, or PEVA (food-safe, water-resistant plastic). Many have a thin foam or felt layer for minimal cushioning.
Pros:
- Ultra-lightweight (usually 0.5–1 pound).
- Rolls up to the size of a water bottle or small umbrella.
- Easy to wipe clean and quick-drying.
Cons:
- Minimal insulation—won’t keep you warm on cold ground.
- Little cushioning for rocks or uneven terrain.
Top Tip: Pair a thin mat with a folded blanket if you want extra comfort without adding bulk.
2. Medium Mats (6–10mm): The All-Rounders
Best for: Most casual picnics, family outings, camping, or trips to rocky/lightly damp areas.
Materials: Typically feature a thicker foam core (EVA or memory foam) wrapped in a water-resistant polyester or canvas top.
Pros:
- Balances comfort and portability (weighs 1–2 pounds).
- Enough cushioning for kids to play and adults to sit for hours.
- Good insulation against mild dampness and cold.
Cons:
- Bulkier than thin mats—may need a carrying bag (most come with one).
Why We Love Them: This is the sweet spot for 90% of picnic-goers. It works for parks, trails, and lakesides without feeling like a chore to carry.
3. Thick Mats (11–15mm): The Luxury Loungers
Best for: Car trips, backyard picnics, beach days, long stays, or families with young kids/elderly members.
Materials: Thick memory foam, cotton-padded layers, or dual-layer foam with a durable, stain-resistant top (like canvas or oxford cloth).
Pros:
- Sofa-like comfort—perfect for napping, playing games, or lounging.
- Excellent insulation against cold, wet ground.
- Durable and long-lasting.
Cons:
- Heavy (2.5–4 pounds) and bulky—hard to carry long distances.
- Takes longer to dry if it gets wet.
Pro Hack: Look for thick mats with foldable designs (instead of rolls) to save space in your car trunk.
Bonus: Other Features to Pair With Thickness
Thickness is important, but it works best when combined with these features to maximize your picnic experience:
- Water Resistance: Look for mats with a waterproof backing (like PEVA or PVC) if you’re using them near water or in damp areas. Even thin mats can be functional if they’re water-resistant!
- Non-Slip Bottom: A rubber or grippy base prevents the mat from sliding on grass or concrete—critical for active kids.
- Size: Thicker mats often come in larger sizes (e.g., 6x8 feet) to fit families, but make sure it’s still foldable/rollable for your needs.
- Easy Cleaning: Spills happen! Choose a mat with a wipeable top (polyester, canvas) instead of absorbent materials (like pure cotton) that stain easily.
Final Checklist: How to Confirm You’re Choosing the Right Thickness
- Terrain: Rocky/damp = thicker (8–15mm); grassy = thinner (2–5mm).
- Users: Kids/elderly = thicker; adults only = medium/thin.
- Transport: Backpack = thin; car = thick.
- Duration: <1 hour = thin; >2 hours = medium/thick.
- Extras: Water resistance and non-slip bottom = must-haves for most outdoor use.
Wrapping Up
Choosing the right picnic mat thickness isn’t about picking the “best” size—it’s about picking the best size for you. A thin mat might be perfect for a solo hike-picnic, while a thick mat could make a family beach day unforgettable. By matching thickness to your terrain, group, and travel style, you’ll ensure every picnic is comfortable, convenient, and free of “why did we bring this?” regrets.
Now grab your mat, pack some snacks, and enjoy the great outdoors—your back (and your kids) will thank you!
