Printable Eye Chart 10 Feet PDF: Where to Get One and Print It Right

The most reliable free printable eye chart for 10 feet comes from the American Academy of Ophthalmology (AAO), which offers separate PDF charts for adults and children designed to be read from 10 feet away. Print it at actual size (not “fit to page”), confirm the largest letter is just under an inch (23 mm) tall, tape it at eye level, and read it from exactly 10 feet with one eye covered at a time.

The rest of this guide covers why the 10-foot distance works, how to make sure your printout is accurate, how to run the test, and what the numbers mean. Details are current as of October 2026; the AAO may update its chart files or instructions, so always follow the instructions printed with the version you download.

Why a 10-foot chart is legitimate

Clinic eye charts are traditionally read from 20 feet (about 6 meters), which is why results are written as fractions like 20/20 or 20/40. Most homes don’t have a clear 20-foot line of sight, so home charts are usually scaled down.

That is fine, as long as the scaling is done properly. In an AAO “Ask an Ophthalmologist” answer, the Academy says charts placed closer than 20 feet are acceptable for distance vision testing if the letter size is scaled to match the distance, and that such charts usually state the recommended testing distance.

The scaling follows from how Snellen letters are built. According to the AAO, each letter is constructed so that it subtends an angle of 5 minutes of arc at the distance the line is designed for. Halve the viewing distance and you halve the letter size, and the angle at your eye stays the same.

What this means for letter heights

Using that 5-arcminute rule, here is roughly how tall the letters on a correctly scaled 10-foot chart should be. These are our own calculations from the AAO’s definition, rounded to one decimal place, so use them as a sanity check rather than an official specification.

The AAO’s printable home charts say the largest letter should be just under an inch (23 mm) tall, which lines up with the 20/100 size at 10 feet in this table. That suggests their chart starts at a smaller line than a classic clinic chart’s big 20/200 “E”. Other printable charts may start at 20/200, so the right top-letter height depends on the chart. Go by the measurement your chart’s own instructions give.

Where to get a trustworthy PDF

Search results for this phrase are crowded with low-quality pages that repost charts without clear sizing information. Stick to sources that tell you the intended distance and the expected letter size:

• AAO home vision test page. The AAO page offers an adult chart, a children’s tumbling-E chart, and a single-E practice card for young kids, with step-by-step instructions.
• Your own eye doctor or pediatrician. Some practices provide home charts for monitoring between visits. MedlinePlus notes that home vision tests are best done under your provider’s direction.

Whatever chart you use, check that it clearly states a testing distance. A chart with no stated distance can’t give you a meaningful score.

How to print the chart at the correct size

Printer scaling is the most common way a home eye chart goes wrong. A PDF that shrinks even a little to fit the page margins will make every line smaller than intended.

1. Open the PDF in a PDF viewer rather than printing straight from a browser preview, if you can.
2. In the print dialog, choose Actual size or 100% scaling. Turn off “Fit to page”, “Shrink oversized pages” or similar options.
3. Use plain white paper and print in black for strong contrast.
4. Measure the largest letter with a ruler. For the AAO chart, it should be just under an inch (23 mm) tall. If your chart has different instructions, use those.
5. If the measurement is off, reprint with corrected settings. Don’t test with a chart you know is the wrong size.

How to run the test at 10 feet

These steps combine the AAO’s instructions and MedlinePlus guidance.

1. Pick the spot. Tape the chart to a wall at eye level. The AAO suggests a wall with no windows, in a well-lit room.
2. Measure 10 feet. Measure exactly 10 feet (3 meters) from the wall and mark the spot on the floor with tape, as MedlinePlus suggests. Stand or sit with your eyes at that mark.
3. Wear your distance correction. If you normally wear glasses or contacts for distance, keep them on.
4. Cover one eye. Cover it with your palm, without pressing on the eye. MedlinePlus advises keeping both eyes open behind your hand.
5. Read from the top down. Read each line aloud until the letters become too hard to make out. A helper can follow along and mark which letters you got right.
6. Record the smallest line you read correctly for that eye, then repeat with the other eye covered. Test the right and left eyes separately.

Testing children

The AAO’s version for kids age 3 and older is a “pointing game.” The child looks at a tumbling “E” and points in the direction its arms face, practicing first with the single-E card. A second adult may need to watch for peeking around the covered eye. The AAO counts a line as passed when the child correctly identifies more than half of the Es on it. Children under 3 should have their vision tested by an ophthalmologist or other eye care professional.

How to read your results

A visual acuity score is a fraction. As MedlinePlus explains, the top number refers to the testing distance, which is often 20 feet in a clinic. The bottom number is the distance at which a person with normal sight could read the same line.

• 20/20 means you read at the standard distance what a person with normal sight reads at that distance.
• 20/40 means you have to be at 20 feet to see what a person with normal vision can see from 40 feet away.
• 20/15 means you see better than average. The AAO points out that 20/20 is not “perfect” vision.

Most 10-foot home charts label their lines with 20-foot-equivalent values, so you can read your score directly from the line label. Check your chart’s key to be sure. If you stand at a different distance than the one the chart is designed for, the labels no longer apply.

What a home eye chart can and can’t tell you

A printed chart measures one thing: how sharply you see high-contrast letters at a distance. The AAO notes that blurry distance vision is most often caused by a refractive error that glasses or contacts can usually correct.

It does not check eye pressure, the retina, the optic nerve, or many other things a professional exam covers. The AAO says home testing is no substitute for an exam and won’t detect serious eye problems or underlying health conditions. Use it to spot a change worth getting looked at, not to rule anything out.

Book an eye exam if your result is worse than you expect, if one eye scores noticeably worse than the other, if a child struggles with the chart, or if your vision changes over time. Any sudden vision change needs prompt professional care, whatever the chart says.
