Munji grain sizes

Paddy is measured with its husk. Green = a typical whole grain; the dashed line = the broken limit (70% of the average length). Tap a card to see how we check it.

Typical sizes of good whole grains; each crop varies a little with the season and the mill.

Quality grades

A
Excellent

Broken up to 5% · other faults up to 4%

B
Good

Broken up to 12% · other faults up to 8%

C
Average

Broken up to 25% · other faults up to 15%

D
Poor

More broken or faults than grade C

Other faults = grains of another type + empty + discoloured grains, as a share of all counted grains. Dust, stones and straw are cut from the weight separately.

Whole

A full grain: at least 70% of the standard length for its type, measured with the husk.

Broken

A grain shorter than 70% of the standard length: often cracked by sun or rough threshing. It gives broken rice at the mill.

Other type (T2, T3)

Grains with a clearly different shape (length ÷ width): often another variety mixed in.

Empty / half-filled

Light, flat husks with little or no rice inside. They float in water and give no rice.

Discoloured

Black, brown or spotted husks, from disease, rain or heating in the stack.

Not counted

Grains that touch, overlap, are blurry or cut off by the picture edge: their length can't be measured.

Check and protect your munji

Moisture decides how long munji keeps and how much whole rice it gives. Then check it with 8 quick tests and store it safely. How to check moisture →

Moisture: the most important number

≤ 12% Seed for next season

Keeps the seed alive and growing well.

12–13% Long storage (6–12 months+) Best

Best for keeping munji a long time without heat, mould or insects.

13–14% Best for milling Best

Gives the most whole rice. Wetter munji is soft and gets crushed; drier than 12% is brittle and breaks.

14% Sell or store up to 6 months

The usual level mills want. Wetter munji gets a weight cut.

15–19% Danger: dry it first

Munji heats up in the stack, gets mould and turns yellow. Never store it like this.

20–24% At harvest

Cut when about 80–85% of the grains have turned golden. Waiting longer makes grains crack in the sun.

How to check munji

8 quick tests before you sell

Check munji from a photo →
  1. Moisture

    Use a moisture meter. Without one, bite a grain: dry munji is hard and cracks with a click; wet munji is soft and chewy.

  2. Empty grains

    Drop a handful in a glass of water: empty and half-filled grains float. Fewer floating grains = better munji.

  3. Colour

    The husk should be an even golden-straw colour. Black, brown or spotted husks mean disease, rain damage or heating.

  4. One variety

    All grains should have the same shape and size. Other varieties or red rice mixed in lower the price, especially for basmati.

  5. Clean

    No dust, stones, straw, mud balls or weed seeds.

  6. Smell and insects

    It should smell fresh, with no musty smell, live insects, holes in grains or powder.

  7. Hand-husk 100 grains

    Rub them between two wooden blocks or your palms and look at the rice: count broken, chalky (milky white) and cracked grains (hold them up to the light).

  8. Size check

    Take a photo on a black cloth and use our free quality check: each grain is measured against the standard size of its variety.

How to protect munji

Keep it dry, clean and safe in storage

Watch it in one minute

Our owl shows every step below, from drying to the 2-week check:

  • Dried to 12–14%
  • Dried the right way
  • On pallets, off the walls
  • Lots kept apart
  • Pests kept out
  • Checked every 2 weeks
  1. Dry it the right way

    Dry on a clean tarpaulin or pakka floor, never on the road or bare soil. Spread it 2–4 cm thick and turn it every 30–60 minutes.

  2. Not too fast

    Strong midday sun or very thin layers crack the grains inside, and cracked grains break at the mill. Cover it in the hottest hours and at night (dew).

  3. Clean store

    Sweep out old grain and dust, fix roof leaks and close rat holes before the new crop comes in.

  4. Good bags, off the floor

    Use new or clean jute/PP bags. Stack them on wooden pallets, about 50 cm from walls, with space between stacks for air and checking.

  5. Keep varieties apart

    Never mix varieties, or old and new crop, in the same bags or heap. Label each stack.

  6. Insects and rats

    Use traps and keep the area clean. Small lots keep well in airtight (hermetic) bags. Fumigation must only be done by a licensed pest-control team; the gas is deadly.

  7. No chemicals nearby

    Don't keep fertiliser, pesticide, diesel or animal feed in the same store.

  8. Check every 2 weeks

    Push your hand deep into the stack: if it feels warm or damp, smells musty or you see insects, dry or sell that lot quickly.

How to protect munji

Questions about munji

What moisture is best for storing munji (paddy) for a long time?

For storage up to 6 months, dry munji to 14% moisture or less. For a long time (6 months to a year or more) dry it to 12–13%. Seed paddy should be 12% or less. Above 14% it heats up, gets mould and insects, and turns yellow.

What moisture is best for milling munji into rice?

13–14%. At this moisture the husk comes off cleanly and you get the most whole rice. Wetter munji (above 15%) is soft and gets crushed; munji drier than 12% is brittle and breaks more. Very dry munji should rest a day or two in a cool, shaded place before milling.

How do I check munji (paddy) quality?

Check the moisture (bite test or a moisture meter), drop a handful in water to see how many empty grains float, look for black or discoloured husks, other varieties, dust and stones, and hand-husk 100 grains to count broken, chalky and cracked rice inside.

How do I protect stored munji from insects and rats?

Store only dry, clean munji in clean bags on wooden pallets, away from walls, in a dry, airy store. Keep rats out, check the stack every 2 weeks for heat, smell or insects, and let only a licensed pest-control team fumigate.
