About RubberDot

Rubber feet, bumpers, and grip dots are the small parts nobody thinks about until something wobbles, slides, marks the floor, or falls off. Get them right and furniture sits square, drawers close quietly, and floors stay unscratched. Get them wrong — the wrong size, the wrong hardness, the wrong way of sticking on — and you get a wobble, a skid, or a bumper on the floor by the weekend. RubberDot exists to put the practical detail behind those little parts in front of you before you buy or fit them.

Rather than long articles you have to read end to end, the site is built around a handful of small, single-purpose calculators, each aimed at one decision. The Rubber Foot & Bumper Size Selectorturns a load into the minimum pad area and diameter that keeps the rubber — and your floor — within a safe pressure. The Durometer (Shore A/D) Hardness Guide makes sense of a hardness number with everyday examples and an approximate cross-scale equivalent. The Adhesive Bond Strength vs Load Calculator checks whether a stick-on bumper will actually hold. The Grip-Dot Spacing & Coverage Calculator plans a grid of dots across an area. The Furniture-Foot Load-Capacity Calculator rates how much a set of feet can carry and the floor pressure it produces. And the Anti-Slip Friction & Coefficient Estimator works out whether something will slide.

Beyond the calculators, the blog and learn section cover choosing feet, durometer and materials, adhesive versus screw-in bumpers, stopping furniture sliding, protecting floors, and the differences between silicone, rubber, and felt, and the Rubber & Materials Museum is a browsable collection on the story of rubber, vulcanization and polymers, fasteners and hardware, and materials science, with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. RubberDot is an independent site, not affiliated with any manufacturer or hardware brand. It is supported by advertising, which is how the tools stay free with no account required. Every result the tools produce — a foot size, a hardness category, a bond safety factor, a dot layout, a load capacity, a friction estimate — is a general estimate built on the numbers you enter and on common engineering conventions, not a professional or certified figure. Material ratings, adhesive strengths, and floor limits vary between products, so for anything that matters, confirm the current specifications with the part and flooring makers before you commit. If a tool looks off, or there’s a calculator you wish existed, the contact page is the place to say so.
