Will It Fit? How to Check Product Dimensions
Published 30 September 2026
A practical way to read length × width × height in millimetres and check furniture, storage and accessory fit before buying a MARC piece.
The short answer
Start with the product's listed length × width × height in millimetres, then measure the actual space where you will use it. Treat those measurements as an outer-size check, not proof that a phone, bottle, plant pot or other object fits inside an opening.
Read the three numbers in the same order
MARC lists measured products as length × width × height, in millimetres. For a quick conversion to centimetres, divide each number by ten: 200 × 150 × 100 mm is 20 × 15 × 10 cm. Compare all three dimensions with your shelf, desk or storage space rather than checking only the largest one.
On a tight shelf, measure the usable space between walls, objects and overhead clearance. Allow a little room to place or remove the item comfortably; the exact allowance depends on your setup.
Outer dimensions are not inner capacity
A jewellery box can fit your dressing table without fitting a particular bracelet. A planter can fit the shelf without fitting your nursery pot. A bottle holder can look right in a photograph without accepting every bottle shape. A phone stand's overall size does not establish compatibility with every phone or case.
If your purchase depends on a particular object fitting into a product, send MARC that object's measurements and ask for the opening or usable interior dimensions. Do not infer capacity from the external dimensions alone.
Check the current listing before checkout
Product pages are the source for the latest dimensions, price and availability. Check the specific product rather than relying on a photo or a similar-looking item. Charge Charm is a phone-stand example; Shell Pearl is a jewellery-box example; It's Showtime is a bottle-display example. Each has a different fit question worth checking.
