Quick answer: If you sell on eBay, Etsy or Vinted, or just send parcels regularly: a postal scale is one of the highest-ROI purchases you can make. Guess your parcel weight wrong and you either overpay postage or get the parcel returned.
The Amazon Basics 65lb Digital Postal Scale is the best pick for most people: it's literally the best-selling postal scale on Amazon, with 0.1oz readability, tare and hold functions, and an AC adapter included. On a tighter budget, the Accuteck ShipPro 110lb is the long-running value champion. Full breakdown of all 6 below.

Why Weighing Parcels at Home Saves Real Money
Royal Mail and every courier price by weight bands. A parcel at 1.9kg and one at 2.1kg can be different prices, and if you underestimate, Royal Mail either surcharges the recipient or returns the parcel to you. Both are expensive in money and reputation if you're selling online.
Weigh at home and you can buy postage online (which is cheaper than post office counter prices), print the label, and drop the parcel off (or book a collection) without queueing. For regular sellers, the time saving alone justifies the scale; the postage savings are a bonus.
The maths is simple: overpay by £1–2 per parcel across 20 parcels a month and a £25 scale pays for itself in the first month. Underpay once and deal with a returned parcel, and you'll wish you'd bought one sooner.
What to Look for in a Postal Scale
Capacity to match your parcels. Letters/small packets: 5kg is fine. Mixed eBay/Etsy parcels: 30kg (65lb). Bulky items: 50kg+. Don't buy a 200kg platform scale for envelopes.
Hold function is essential. A big box covers the display while weighing: hold freezes the reading so you can read it after removing the parcel. Non-negotiable for parcels.
Tare/zero button. Zero out the box or padded envelope to get the true contents weight. Every scale here has one.
Readable display. Backlit LCD minimum; a separate or extended display (Accuteck, Rollo) is even better for large parcels.
Grams and ounces. Royal Mail uses grams; many couriers and US buyers think in ounces/pounds. A scale that does both saves mental maths.
AC adapter or long battery life. If the scale lives on your packing desk, an AC adapter (included with most here) beats buying batteries forever.
The best-selling postal scale on Amazon: thousands bought every month, and the reviews explain why. 0.1oz readability up to 65lb/30kg, tare and hold functions, a counting (PCS) mode for identical items, and an AC adapter included so it can live permanently on your packing desk. Backlit LCD, auto-off, batteries included as backup.
Our take: This is the default recommendation for a reason: it does everything a home or small-business shipper needs, it's the category best-seller by a mile, and Amazon's own warranty backs it. Unless you have a specific reason to choose otherwise (heavier parcels, tiny desk), buy this one.
Pros
Best-seller: proven at scale
0.1oz readability, 30kg capacity
AC adapter + batteries included
Hold, tare and PCS counting modes
Cons
Display fixed to base (large boxes can cover it, so use hold)
The ShipPro has been the value king of postal scales for a decade. 110lb/50kg capacity with 0.1oz graduations, an extended backlit display on a cable (so big parcels never hide the reading), fold-up mailer holders for tubes and envelopes, and triple power: batteries, USB cable and AC adapter, all in the box.
Our take: More thoughtful design than anything else near this price. The extended display alone is worth it if you ship awkwardly-shaped parcels. The 12,000+ ratings are earned. If the Amazon Basics feels too plain, this is the upgrade that costs barely more.
MUNBYN built its name on label printers for ecommerce sellers, and this scale is designed for the same desk. 66lb/30kg capacity, 0.1oz readability, and a 90° flip-up holder that keeps envelopes and tubes upright while weighing. Hold, tare and PCS counting, five units (g, kg, lb, oz, lb:oz), backlit LCD, batteries and AC adapter included, plus a tape measure in the box, a nice touch.
Our take: The small-business specialist. If you already use MUNBYN's printers, this fits the workflow perfectly, and the flip-up holder genuinely helps with the awkward padded envelopes that slide off flat scales. Slightly pricier than the Amazon Basics, but the extras justify it for regular shippers.
From the makers of the popular Rollo label printer, this scale is built for sellers who weigh parcels all day. 110lb/50kg capacity with 2g accuracy, hold and tare, and a separate swivel LCD panel you can angle for easy reading from anywhere at the packing bench. AC adapter and AAA batteries included, auto-off after 2 minutes.
Our take: The premium-feeling option for serious sellers. The swivel display is genuinely useful when you're weighing box after box, and the Rollo ecosystem (printer + scale) is a smooth workflow. You pay a bit more than the Accuteck for similar specs; the money goes into build and brand trust.
The M5 is the classic desk-drawer postal scale: 5lb/2.2kg capacity, 1g readability, hold and tare, and a footprint small enough to store in a desk drawer. LCD reads in lb/oz or kg/g. Three AAA batteries included, auto-off to save them. It's been the go-to for home offices for years.
Our take: Perfect if you only ever send letters and small packets. The limitation is obvious: 2.2kg won't cover most parcels, so be honest about what you ship. As a second scale for the office desk (letters only), it's ideal. As your only scale for parcels, it's not enough.
When 30kg isn't enough: 440lb/200kg capacity with 10g readability, a large stainless steel platform, and a detachable display on a long cable that you can wall-mount. Hold and tare, three units (lb, lb:oz, kg), AC adapter and batteries included, 2-year warranty. Built for warehouses, workshops and anyone shipping genuinely heavy items.
Our take: Serious overkill for home use, and that's the point. If you're weighing car parts, bulk stock or furniture parcels, this is the cheapest way to do it accurately. For everyone else, the 65lb models above are more precise at the weights you'll actually weigh.
We didn't test these scales hands-on, and we won't pretend we did. We compared current options on capacity, readability, hold/tare functions, display design, power options, and reliability signals from the buyer base (including best-seller rankings in the Postal Scales category). We excluded no-name brands with no support, scales with dead listings, and industrial platform scales far beyond home/small-business needs.

Frequently Asked Questions
Do I need a postal scale to send parcels?
Not strictly, but without one you're guessing. Royal Mail and couriers charge by weight bands, and guessing wrong means overpaying or having parcels returned. A £20 scale pays for itself fast if you ship regularly.
What capacity postal scale do I need?
Letters and small packets: 5kg is plenty (the DYMO M5 covers this). Mixed parcels for eBay/Etsy: 30kg/65lb (Amazon Basics, MUNBYN). Heavy/bulky items: 50kg+ (Accuteck, Rollo) or 200kg (Fuzion).
What is the hold function on a postal scale?
Hold freezes the weight on the display after you remove the parcel: essential when a large box covers the screen during weighing. All the parcel scales in this guide have it.
Are cheap postal scales accurate?
Yes, for postage. Postage bands are wide (usually 100g+ steps), so even ±10g accuracy is plenty. Capacity, hold function and a readable display matter far more than laboratory precision.
Can I use a kitchen scale as a postal scale?
For letters and packets under 5kg, yes. But kitchen scales lack hold functions and their displays disappear under parcels. If you ship more than occasionally, get a dedicated postal scale, or see our best kitchen scales guide if cooking is the main job.
How do I convert parcel weight for postage?
Royal Mail prices in grams; most scales show g, kg, lb and oz. Use our parcel weight converter if your scale reads in units your courier doesn't use.
Our Top Pick: Amazon Basics 65lb
The best-selling postal scale for a reason: 0.1oz readability, 30kg capacity, hold/tare/counting, AC adapter included. Weigh your next parcel at home, buy the right postage online, and never queue at the post office with an overweight parcel again.
