1/4 cup of panko is about 12.5 g — roughly a quarter of the 50 g that a full cup weighs spooned and levelled, according to King Arthur Baking. This page gives you that answer in context: the full conversion table, three worked recipe examples, and the measuring method behind the number.
1/4 cup of panko in grams

| 1/8 cup | 6.2 g |
| 1/4 cup | 12.5 g ← this page |
| 1/3 cup | 16.7 g |
| 1/2 cup | 25 g |
| 2/3 cup | 33.3 g |

All figures are approximate. One US cup of panko weighs 50 g spooned and levelled (King Arthur Baking), and every fraction above is calculated from that figure. When the result matters — a cake, a loaf, a sauce you cannot remake — verify with a kitchen scale.
What 1/4 cup of panko looks like in the kitchen
1/4 cup of panko is a modest heap — about four tablespoons, or a small handful if you are working with a dry ingredient. In a standard measuring cup it fills the cup to the 1/4 cup line, but volume alone does not tell you the weight, because panko settles differently depending on how you fill the cup Light, airy Japanese breadcrumbs; very low density per cup. The safest way to picture it is on the scale: tare your bowl, pour or spoon panko in until the display reads about 12.5 g, and stop. That reading is worth more than any mental image of a heap or a level cup, because it does not depend on how hard you pressed or how humid the day is.
Worked examples
Example 1: a recipe that lists weight for everything else
Your recipe gives flour in grams and butter in grams, then suddenly asks for 1/4 cup of panko. Stay in grams: 12.5 g keeps every ingredient on the same system, and your scale does the work. Add panko to the bowl on the scale until the display reads 12.5 g, then move on to the next ingredient.
Example 2: doubling from 1/4 cup to 1/2 cup
You liked the recipe and want to double it, so 1/4 cup becomes 1/2 cup. That is 25 g of panko. Weighing the doubled amount is easier than filling a 1/4 cup cup twice, because a second scoop rarely matches the first. One weighing of 25 g is both faster and more accurate.
Example 3: checking a recipe that seems off
If a cake comes out dense or a sauce comes out thin, the first suspect is the measuring. A recipe that asked for 1/4 cup of panko was written for about 12.5 g. If you scooped a packed cup instead, you may have added far more. Next time, weigh the 12.5 g and compare the result — it is the quickest way to find out whether the recipe or your measuring was at fault.
How 1/4 cup of panko is measured
The figure of 12.5 g is based on panko measured spooned and levelled, following King Arthur Baking. One full cup weighs 50 g under that method, and 1/4 cup is simply that figure multiplied by 0.25. That is why the headline number is labelled approximate: it is a calculation from a published full-cup density, not a measurement of the exact spoonful in your kitchen.
If your panko was measured differently, the weight changes. A scooped cup packs more in; a sifted cup holds less; a packed cup of a sticky ingredient holds far more than a spooned one. The method matters as much as the number, which is why every conversion on this site states its method alongside its source. When a recipe matters — a celebration cake, a loaf of bread you have been planning, a sauce you cannot remake — weigh the panko on a kitchen scale and let the scale settle the argument. 12.5 g is a good target; the scale tells you when you have actually hit it.
King Arthur Baking is the source for the full-cup figure, and this site uses that value consistently across every panko page, so the quarter-cup, half-cup and full-cup figures all agree with each other. If you have seen a different number elsewhere, it almost certainly comes from a different method or a different source's rounding — not from a different ingredient.
Practical guidance for panko
Crispy coatings for fried and baked foods. Light, airy Japanese breadcrumbs; very low density per cup. That character is why the weight matters more than the volume: panko does not settle into a cup the same way twice, so two level cups can weigh noticeably different amounts.
Storage changes the number too. Airtight container, cool and dry, up to 6 months. An ingredient that has absorbed moisture, or one that has settled and compacted in its container, weighs more per cup than the same ingredient freshly opened. Keep it sealed and give it a stir before measuring.
The most common failure with panko is treating a level cup as a precise amount. It is not — it is an approximation that depends on how you filled it. Weighing 12.5 g for 1/4 cup is the only way to know you have the same amount the recipe author used.
Common mistakes with 1/4 cup of panko
Using a liquid measuring jug for a dry ingredient (or the reverse). Dry cups and liquid jugs are not interchangeable, and the meniscus on a jug makes small dry amounts hard to read.
Forgetting to tare the scale. Weighing the bowl as well as the panko adds its weight to your reading, so always press tare with the empty bowl on the scale first.
Measuring over the mixing bowl. Spills fall into the recipe and cannot be taken out cleanly. Measure over the bag, the sink, or a spare plate instead.
If you do not have a scale
For sticky or pourable panko, lightly oil the measure first so it releases cleanly, and pour slowly so you can stop at the line.
Use a 1/4 cup measure if you have one. Fill it using the spooned and levelled method: spoon panko in, do not press it down, and level the top with the back of a knife.
Four level tablespoons are roughly 1/4 cup of a cup — about 12.5 g of panko. Tablespoons are easier to level accurately than a small cup, so this is a decent fallback.
Remember that any of these fallbacks is approximate. A kitchen scale is inexpensive, and it turns every conversion on this site — including this 12.5 g figure — from a good guess into a measurement you can trust.
Frequently asked questions
Why do different websites give different grams for 1/4 cup of panko?
Because the full-cup figure differs between sources. King Arthur Baking lists 50 g per cup spooned and levelled, and other sources may scoop, pack or sift differently. Packing, brand and humidity all shift the true density a little, and different sources round their figures differently. The differences are usually small for 1/4 cup, but they explain why you see several figures online.
How do I measure 1/4 cup of panko without a scale?
Use a 1/4 cup measure and the spooned and levelled method: spoon the panko in loosely, level the top with a straight edge, and do not pack it down. Four level tablespoons are the same volume. Expect the result to be approximate, and use a scale for baking where precision matters.
What is the best way to store panko so the conversion stays accurate?
Airtight container, cool and dry, up to 6 months. Keeping panko dry and settled matters, because clumping and moisture change how much fits in a cup — and therefore how much a cup weighs.
Should I sift panko before measuring 1/4 cup?
Only if the recipe says to. Sifting adds air and lowers the weight per cup, so 1/4 cup of sifted panko weighs less than 1/4 cup measured spooned and levelled. The 12.5 g figure here assumes panko measured spooned and levelled, not sifted — unless your recipe explicitly says 'sifted'.
How many tablespoons is 1/4 cup of panko?
1/4 cup of a cup is four tablespoons by volume. By weight that is about 12.5 g of panko. Tablespoons are a useful fallback when you do not have a 1/4 cup measure, but weigh the result if you can, because a heaped tablespoon is not the same as a level one.
