Koopbuy Spreadsheet Categories

The best category is not the one with the most rows. It is the one that lets you apply a consistent set of checks without switching standards halfway through.

Pick a lane

Start with the product type you actually want, then compare rows inside that category for useful photos, dimensions, fit, price context, source relevance, and shipping weight. This makes weak entries easier to remove.

Seven practical lanes

Browse by the evidence you need

All external buttons below use Findsindex global category pages and open in a new tab.

Footwear

Shoes & sneakers

Shoes are unforgiving when the size or shape is wrong. Compare similar pairs so differences in the toe, heel, sole, and profile are easier to see.

Look for: side and rear profiles, sole shape, toe shape, close details, a usable size chart, and approximate packed weight.

Carry

Bags

A front photo can hide the things that make a bag frustrating: the opening may be narrow, the strap too short, or the interior smaller than it looks.

Look for: dimensions, interior view, hardware, stitching, closure, strap points, base, and how it holds shape.

Layering

Hoodies

For hoodies, the letter on the size button tells less than the actual chest, length, sleeve, and fabric weight. Decide whether you want a trim or relaxed fit first.

Look for: garment measurements, fabric weight, inside texture, hood construction, cuffs, hem, and intended fit.

Parent category

Shirts, jackets & pants

Split clothing into the piece you actually want. A jacket, T-shirt, pair of pants, shorts, and jersey need different measurements and should not share one shortlist.

Look for: size chart units, chest and length, rise and inseam, fabric, lining, pocket details, and season.

Wrist

Watches

Start with scale. A close photo can make almost any watch look substantial, so compare the case dimensions and a wrist view before small dial details.

Look for: case diameter, thickness, dial and crown details, clasp, wrist scale, and careful wording around specifications.

Small goods

Accessories & headwear

Small items need a clear reference for size. Check what is included and how the closure, edges, and contact points are finished.

Look for: measurements, a photo for scale, closure, edge finishing, material description, and included pieces.

Browse global accessories

Compatibility

Electronics

Do not save an electronic item until the exact model and region are clear. A visually identical version can use a different plug, protocol, voltage, or software.

Look for: exact compatibility, power or battery notes, plug or protocol, included parts, package weight, and support policy.

Which category should you start with?

Start with the item type that would make you most disappointed if the dimensions, fit, or construction were wrong. For footwear, that often means size and shape. For a bag, it may be scale and interior layout. For clothing, measurements usually beat the letter printed on a size button.

If you are browsing several types, create separate shortlists. A heavy jacket and a small accessory should not be judged by the same price or weight assumptions.

Mistakes to avoid

Opening every row because it sits under a familiar category label.
Comparing only prices while ignoring the amount of visible evidence.
Using one generic QC standard for every product type.
Treating a source label as a seller or quality verification.
Forgetting that packaging can change a lightweight-looking item.
Using an external category page as proof that a particular listing is suitable.

Checklist before opening external pages

I know the exact category I am comparing.
I can name two or three photo angles or details that matter.
I know whether measurements, compatibility, or fit notes are essential.
I will compare similar rows before reacting to the price.
I have a weight or packaging question ready if the item could be bulky.
