See how big a product really is
Upload a product image, type its real dimensions in cm, mm, m, inches or feet, and see it drawn to scale next to a 180 cm man, a woman, a child, a soda can or a banana. Runs entirely in your browser.
Nothing is uploaded — everything runs in your browser.
Free plan: 3 exports a day and a 10 MB image cap. Pro removes both and unlocks 2x export.
What people use it for
- Show webshop customers how big a product actually is before they buy, and cut size-related returns.
- Add a “scale” image to an Amazon, eBay or Etsy listing where buyers can't handle the item.
- Explain furniture, art prints, rugs or planters in a room-sized context without a photo shoot.
- Compare a new product against a person for a spec sheet, pitch deck or trade-fair poster.
- Check whether a machine, flight case or pallet is realistically carryable by one person.
- Give social posts an instantly readable size cue — including the classic banana for scale.
- Help interior and event clients judge signage, displays or stand elements before production.
This free product size comparison tool answers the single question product photos are worst at: how big is it, really? Upload a photo, type the real dimensions, and see the item drawn to scale next to a person — a 180 cm man, a 165 cm woman, a child, a soda can, or a banana for scale.
Online shoppers can't pick an item up, and a close-up on a white background gives them no reference at all. That mismatch is one of the most common reasons for returns on furniture, lighting, art prints, planters, tools and packaging. A single size comparison image in the gallery fixes it: the buyer sees at a glance whether the lamp is desk-sized or floor-sized, whether the print is A4 or a statement piece, whether the crate needs two people.
You can switch between cm, mm, metres, inches and feet, set the exact height of the reference person, turn on height guide lines, and combine several references in one graphic. The export is a clean, watermark-free PNG — with a transparent background if you want to drop it onto your own brand layout.
Everything runs locally in your browser: your product image is never uploaded, which matters when the product hasn't launched yet or belongs to a client under NDA.
How it works
- 1
Upload the product photo
Drag in a JPG, PNG or WebP. Transparent or white borders are cropped away automatically so the measurements line up with the visible product.
- 2
Type the real dimensions
Enter width and height in the unit you measure in — mm, cm, m, inches or feet. Keep the photo's aspect ratio locked and one value fills in the other.
- 3
Pick your references
Man, woman, child, soda can or banana — as many as you like, each with an adjustable height for the people.
- 4
Export the comparison
Download a watermark-free PNG, optionally with a transparent background and height guide lines, ready for your product gallery or a spec sheet.
