Dolch vs Fry Sight Words: What's the Difference, and Which List to Use
By Readigo editorial team · 2026-07-21 · 7 min read
Short answer
The Dolch list (1936) has 220 "service words" plus 95 nouns, grouped into grade bands from pre-primer through 3rd grade. The Fry list (updated 2000) has 1,000 words ranked purely by how often they appear in print, usually taught 100 at a time. They overlap heavily - nearly every Dolch word appears in Fry's first 300 - so for a parent the choice matters less than it looks. Use Dolch's grade bands for a young child starting out, and Fry's frequency order once you're past the first couple hundred words. Or use a combined list and skip the debate entirely - that's what our sight words checklists do.
What the Dolch list is
Edward Dolch built his list in the 1930s by finding the words that appeared most often in the children's books of his era. He deliberately left out most nouns, on the theory that nouns are tied to specific stories, while the "service words" - pronouns, verbs, prepositions, conjunctions like “the”, “was”, “because” - appear everywhere. The result: 220 service words split into five levels (pre-primer, primer, 1st, 2nd, 3rd grade), plus a separate list of 95 common nouns. The grade bands are the Dolch list's superpower and the reason schools still use it 90 years later. A kindergarten teacher doesn't need a thousand-word ranking - they need to know which 40 words to put on the wall in September. That's the pre-primer list. The age of the list is its weakness. It was drawn from books kids read in the 1920s and 30s, so it includes a few words that have faded (“shall”) and misses vocabulary that dominates children's print today.
What the Fry list is
Edward Fry took a different approach: rank the 1,000 most frequent words in printed English for grades 3-9, in pure frequency order, and update the ranking from modern corpora (his last revision was 2000). No grade bands, no theory about nouns - just frequency. Schools teach it in chunks: the "first hundred," "second hundred," and so on. The numbers behind it explain why it works: Fry's first 100 words make up about half of everything printed in English. The first 300 make up about 65%. That's why a child who reads the first few hundred instantly suddenly sounds fluent - most of every page is already automatic. Fry's strength is its reach. Dolch stops at 315 words and 3rd grade; Fry keeps going to 1,000, which is why our grade 4 and grade 5 checklists draw from Fry's fourth and fifth hundreds - there is no Dolch equivalent at that level.
The actual differences
Size: Dolch has 220 service words (315 with nouns); Fry has 1,000. Organization: Dolch groups by grade level, which tells a teacher or parent what to teach when. Fry ranks by frequency, which tells you what pays off fastest. Age: Dolch reflects 1930s children's books; Fry was updated in 2000 from modern text. Nouns: Dolch separates them out; Fry mixes everything together. Coverage: they agree far more than they differ. Almost all 220 Dolch service words sit inside Fry's first 300. If your child masters either early sequence, they've mastered most of the other one for free. What neither list is: a phonics program. Both are frequency lists. Most words on both lists follow regular spelling patterns and should be decoded, not memorized whole - the modern approach is to sound out what's regular and learn by heart only the truly irregular part (“said”, “was”, “of”). Our checklists mark those heart words for exactly this reason. (More on that distinction: sight words vs decodable words.)
Which list should a parent use?
Honestly: whichever one your child's school uses, so home practice matches classroom testing. Ask the teacher - it's a one-line email. If you're choosing from scratch, the practical answer is a hybrid, and it maps to age: Kindergarten and 1st grade: Dolch's structure wins. The pre-primer and primer bands are the right size and the right words for a brand-new reader. Start with the kindergarten checklist. Grades 2-3: the lists converge. Any combined high-frequency sequence works; what matters is daily practice and reading the words in real books, not which list they came from. Grades 4-5: Fry is the only game in town - Dolch ends at 3rd grade. If an older child still stumbles on common words, Fry's fourth and fifth hundreds tell you exactly which tier to check. Our checklists merge the two lists, deduplicate them, and order them roughly by frequency within each grade - so you can work through kindergarten to grade 5 without ever picking a side.
Where Readigo fits
A list tells you which words to practice. It can't tell you which words your child actually reads instantly versus which ones they hesitate on - that takes someone listening, every time they read. Readigo is that listener: it hears your child read aloud, flags the words that get misread or ground out slowly, and tracks which high-frequency words have become truly automatic. So instead of drilling all 100 words on a checklist, you drill the eleven that are actually still slow - and the list stops being homework and becomes a scoreboard.
The bottom line
Dolch and Fry are two rankings of the same truth: a small set of words does most of the work in English text. Dolch gives you grade-sized chunks and stops at 3rd grade; Fry gives you frequency order and goes to 1,000. Pick the one your school uses, or use a merged list and spend the saved energy on what actually builds readers: daily practice, real books, and someone who catches the words that don't stick.
