CupClarityMy notebook Hario V60 01 vs 02 vs 03: Sizes, Filters & Daily Batch Planning
Compare the three V60 sizes by your actual brew volume, filter supply and serving routine—not just the number of cups on the box.
Research-based guide, not a hands-on test. Official facts are attributed below. Calculations and suggested comparisons are editorial examples, not measured product performance.
| Question | What to compare | Next step |
|---|---|---|
| 01 | HARIO: 1–2 cups | Check your usual single-serving recipe |
| 02 | HARIO: 1–4 cups | Compare daily and occasional shared batches |
| 03 | HARIO: 1–6 cups | Verify server size and filter availability |
| Any size | Brew water is not finished yield | Measure the beverage you actually serve |
What do 01, 02 and 03 mean?
HARIO Europe lists 01 for 1–2 cups, 02 for 1–4 and 03 for 1–6. These are manufacturer serving ranges, not a promise that six large travel mugs fit one preparation. Start by measuring the amount you normally brew. Record coffee dose, total brew water and the finished amount you pour into each mug separately.
One person: begin with the recipe, not the largest size
Write down three ordinary mornings rather than a hypothetical dinner party. If your recipe is repeatable and fits your current brewer, a larger cone alone is not evidence of a better cup. For a new purchase, compare the exact model dimensions with your mug opening and storage space. Check that the base sits securely. This is a practical shopping checklist, not a recommendation to balance an unverified dripper on a narrow cup.
Two people: distinguish brew water from finished coffee
An illustrative recipe using 30 g coffee and a 1:16 ratio needs 480 g brew water. That does not guarantee two finished 240 ml mugs: grounds retain water and the actual beverage yield must be measured. If your goal is two generous servings, work backward from your observed yield. Do not equate the full water dose with the amount held in the cone at one time; pour-over recipes add water progressively.
Compare all three filter supplies before buying
Read the size on both the dripper and the filter packaging. Include filter availability and delivered cost in the decision, especially if your local shop carries only one size. Our buying approach is to choose the matching paper size rather than assume an improvised fit will behave identically. A folded or undersized filter changes the setup you are comparing. Check seller photographs and model codes instead of relying on a generic V60 listing title.
Does changing size require a new grind setting?
We cannot prescribe a universal number of grinder clicks from the dripper number. If you change brewer and batch size together, the old recipe is no longer a controlled comparison. Keep the coffee and water ratio recorded, then note grind setting, pouring sequence, total time and taste. Adjust one variable for the next trial. A longer time by itself does not establish that the new dripper is faulty or that the coffee must taste worse.
V60 size and Switch capacity are different questions
This guide concerns the regular V60 size decision. A Switch adds a valve and can hold a closed immersion stage, so do not apply the V60 cup range as its closed-valve liquid capacity. Check the specific Switch product specification and recipe. If your real choice is immersion control versus a standard pour-over workflow, read that comparison before choosing the number on the box.
A purchase worksheet you can reuse
Record your usual dose, water input, measured output, number of drinkers, available server and local filter size. Then list the exact product you are considering and verify its dimensions. If occasional guests are the only reason to change, compare a second batch against a bigger setup. There is no universal winner without knowing the routine; the useful choice is the one whose limits you have checked.
