Custom Magnetic Bumper Stickers

Choosing Sizes for Custom Magnetic Bumper Stickers

Bumpers on most modern cars are plastic, which magnets do not stick to, so magnetic bumper stickers usually go on the boot lid, tailgate or rear wing, where the panel is steel. Look for a flat or gently curved area; a magnet cannot follow a sharp crease or a tight curve.

Common sizes range from around 200 by 75 mm for a compact message to 300 by 100 mm for a standard bumper-style design. Round and oval magnets of 100 to 150 mm suit logos and badges. Larger magnets offer more visibility but need a larger flat area, so check the vehicles your audience drives before choosing a big size.

If you are not sure, order two sizes. A compact version fits small hatchbacks and a larger one suits estates, vans and SUVs.

Before ordering a large batch for a giveaway, test a sample on a few different cars. A quick check on a hatchback, a family estate and a small van shows whether the size and shape suit the steel areas people actually have, and avoids handing out magnets that only fit some vehicles. p3 The guide to measuring a product covers checking flat areas before sizing.

Magnet Thickness and Grip

Magnetic sheet comes in different thicknesses. Thinner magnets are lighter, cheaper and fine for small designs used around town. Thicker magnets grip more strongly and are better for larger designs and motorway driving. For most bumper stickers, a mid-thickness sheet gives a good balance of grip, flexibility and cost.

Grip depends on contact. A magnet holds best when its whole surface is flat against clean, dry steel. Air gaps, dirt or wax reduce grip, and a magnet placed over a body line or trim may lift at speed.

Magnets also suit fridges, filing cabinets, lockers and metal doors, which makes them a versatile giveaway. A supporter who does not want a sticker on their car may happily put the same magnet on the fridge, so your message still gets seen every day. p2 Hard hats and site lockers take our hard hat stickers in tough vinyl rather than magnets.

Care Tips for Drivers

Clean the panel and the back of the magnet before fitting, and make sure both are dry. Remove the magnet before going through an automatic car wash, and take it off every week or so to clean underneath, which stops moisture and grit becoming trapped against the paint.

Store magnets flat when not in use, never rolled or folded, and avoid leaving them on a very hot panel in full sun for long periods, as heat can soften the magnetic layer. On new paintwork, wait until the paint has fully cured before applying any magnet.

We include a short care card with orders on request, which is handy if you are handing magnets out to customers or supporters. p2 Laminate choices are compared in the guide to print and finish options.

Popular Uses for Magnetic Stickers

Businesses use them as promotional giveaways at shows and in-store, printed with a logo and slogan. Campaigns and charities use them for awareness messages and fundraising. Sports clubs and supporter groups print team crests and slogans. Driving schools, delivery drivers and community transport schemes use them to show temporary information on private cars.

Car owners also order them for personal messages, family notices and humour, enjoying the freedom to change or remove them without leaving a mark.

Event organisers sometimes print magnets for marshals and volunteer drivers, so cars on site can be identified quickly without any permanent branding. When the event is over, the magnets are collected, stored flat and reused the following time.

Test One Magnet on Three Different Cars

Magnetic bumper stickers rarely go on bumpers, because most are plastic; they go on boot lids and tailgates, and the flat steel area there varies by car. Before you order a giveaway run, ask for a single sample in the size you have in mind and try it on a hatchback, an estate and a small van. If it bridges a body line on any of them, drop a size. Send the shape, the size that passed and the quantity.

Keep the message to a few words in large type, because the car behind has two seconds to read it, and ask for a UV laminate if the magnets will live outside all summer. The custom quote arrives by email within one working day, from £0.25 for small magnets, with the minimum set per job.

The free proof shows the cut line and the print; mention any show or campaign date so the proof stage is planned round it. Production takes 4 to 7 working days after approval and the magnets reach UK mainland addresses by free tracked delivery. Businesses that brand a whole vehicle add magnetic signs for car doors in the same artwork.
