Everyday Size Compare

What it is for

Will the new monitor dwarf the old one? Does the corner sofa eat half the living room? Product photos never show size honestly, but a scale drawing from the dimensions on the data sheet does. Enter up to eight objects with width, height and depth, choose a view, and the tool draws them as rectangles on one shared scale, either overlaid on a common baseline or side by side. A table lists every dimension relative to the first object.

The drawing uses bounding boxes. It shows how much space something occupies, not its shape, and it does not check whether a sofa fits through a door or around a staircase.

Worked example

The default compares two monitors in millimetres, front view, overlaid: an Old monitor of 540 × 330 × 60 mm and a New monitor of 710 × 420 × 70 mm. The table shows the new one at 1.315 times the width and 1.273 times the height of the old one, and a Bounding volume of 20.874 l against 10.692 l.

A living-room example in Centimetres (cm), Top view, Side by side:

The result: "Compared 3 objects in top view." The table converts everything to millimetres. The corner sofa is 1.289 times as wide and 1.778 times as deep as the old sofa, and its bounding volume is 3,136 l against 1,453.5 l. In top view you see the footprint: the new sofa covers 245 × 160 cm, wider and deeper than the 200 × 140 cm rug, which the old sofa (190 × 90 cm) did not.

How to read the result

• The drawing shows each object as a rectangle in the chosen view: Front view uses width and height, Side view depth and height, Top view width and depth. All objects share one scale, so twice as long on screen means twice as long in reality.
• Overlay stacks the rectangles on a common baseline, which is best for "how much bigger". Side by side lines them up next to each other, which is best for floor space.
• The Objects table lists Width (mm), Height (mm), Depth (mm), Bounding volume (l) and the three ratios against the first object. A ratio of 1.5 means 50 % larger in that direction.
• Vector SVG downloads the dimensioned sketch; CSV and Result JSON export the numbers.

Tips and common mistakes

• Put your reference object first, such as the item you already own. All ratios are measured against row 1.
• Mixed units are a classic error: enter all rows in the unit chosen under Input unit. Inch values in a centimetre table make an object 2.54 times too small.
• Use manufacturer dimensions including stands, feet and handles. A monitor stand often adds 10 cm of height.
• Bounding volume overstates L-shaped or rounded objects. For a corner sofa it is the box around the whole L.
• For a fit check, add the space itself as an object, such as a niche of 250 × 180 cm, and compare in top or front view.

FAQ

Can I compare more than two objects?

Yes, up to eight rows. Every row is compared with the first.

Does the tool check whether furniture fits through a door?

No. It compares rectangles on one scale. Turning a sofa through a doorway depends on diagonals and angles that a 2D sketch does not model.

Why does a thin object have almost no volume?

Volume is width × height × depth. A rug 1 cm high has a large footprint but only 28 l of bounding volume, so compare floor items in top view.

Which units can I use?

Millimetres, centimetres or inches. The result always shows millimetres so that mixed sources become comparable.
