The blend is the constant; storage, cash outlay and finish time are the variables. Choose the smallest pack that comfortably reaches your next sensible reorder.
What actually changes between sizes
These are size variants of Tetley Original rather than four different blends. The useful comparison is total tea weight, box price, cost per bag, cupboard space and the number of days the box will be open. Packaging can also vary by market and batch, so current pack disposal instructions outrank an old general claim.
Match the box to weekly cups
Five cups a week would make 40 bags last about eight weeks and 400 last roughly 80. Twenty-eight cups a week—four a day—uses 40 in ten days, 80 in under three weeks, 240 in about two months and 400 in a little over three. That simple calculation is more reliable than “family size” wording.
Where the apparent saving disappears
A low pence-per-bag figure can be lost through stale aroma, crushed bags, damp storage or simply growing tired of one blend. Large packs work best when the tea is already a known favourite. New customers should establish that with 40 or 80 before buying 400.
The unsupported 1,100-bag claim
No live Tetley Original 1,100-bag product supports that proposed figure in the current catalogue, so it is deliberately excluded. Search snippets and old trade listings are not enough for a current buying guide. If a verified live format appears later, it can be added with a dated product source.

The practical buying decision
- 40 bags: trial, occasional drinker or limited storage.
- 80 bags: the sensible default for many homes.
- 240 bags: frequent family use or a smaller shared kitchen.
- 400 bags: high turnover with dry, airtight reserve storage.
Use fresh water and a consistent steep when moving between boxes; pack size should not change the brewing standard.

How we keep this guide useful
Teas.co.uk is the retailer and the editor of this guide. No brand paid for inclusion or position. We start with products that are published and in stock in our own shop, then separate comparable products by tea family, ingredients, format, caffeine position and intended use. “Best” means the best fit for a stated need within this dated shortlist—not a universal tasting result.
Product names such as Sleep, Digest, Defence, Detox or Immune are treated as range labels, not medical evidence. Always read the current ingredient, allergen and preparation information on the pack. If you are pregnant, take medicines or manage a health condition, check ingredients such as liquorice root with an appropriate clinician. Last editorial and catalogue review: 8 August 2026.
