SIZE GUIDE FAQ
Waterproof blanket size questions
Quick answers to help you choose the right size for beds, sofas, pets and car seats.
What size waterproof blanket should I choose for a bed?
Start with the width and length of the part of the bed you want to cover. If you want more overhang or shared coverage, moving up a size often gives more flexibility.
What size is best for a sofa?
Smaller sizes can work well for seat cushions, pet spots or a single sitting area, while larger sizes usually suit wider sofas or broader surface coverage.
What size is best for pets?
Choose a size based on the resting area you want to protect. Smaller sizes are often useful for crates, chairs, car seats or one pet zone, while larger sizes cover broader shared spaces.
What size is best for car seats?
Compact sizes are usually easiest to position on car seats or back seats. Measure the seating area first if you want more exact coverage.
Should I size up?
If your measurements are close to the next size or you want more side coverage, sizing up is often the safer choice.
Is the blanket meant to cover the whole mattress?
Not necessarily. Bedding Aid waterproof blankets are designed as flexible top-layer coverage rather than fitted mattress covers, so many customers choose the size that protects the main area they use most.
