How to Transfer Growth Chart Marks to a New Canvas When You Upgrade
To transfer growth chart marks to a new canvas, read each old mark as a height in inches, check a couple of those readings against a tape measure, and draw each mark where the new chart's scale shows the same number. Don't trace the lines across by position, because two charts rarely start their scales at the same height. Then keep the old chart as the original.
Maybe the first chart was a baby shower gift that tops out at four feet. Maybe it was printed in centimeters, or your oldest is a hand's width from the top, or a new sibling needs room. Either way, you want the bigger canvas to start with every mark you've already made, not a blank stretch where the early years should be.
This guide walks you through how to transfer growth chart marks to a new canvas accurately: what to check before you buy, how to log the old marks, how to catch a chart that hung at the wrong height, and how to move height marks to the new growth chart neatly. Plan on an unhurried hour and a tape measure.
Why can't you just line the two charts up?
In short: match the numbers, not the positions.
Every growth chart is designed to hang a set distance off the floor, and its printed numbers only work at that height. One chart's scale might begin at 6 inches, another at 12, another at the floor. Some use centimeters.
Hold two charts side by side and trace across, and each mark can land in the wrong spot, even though the lines look tidy. So treat the old chart as a list of numbers. A line at 38 1/2 inches on the old scale gets drawn at 38 1/2 inches on the new one, wherever that falls on the fabric.
What should the bigger chart have?
If you're about to upgrade your growth chart canvas and haven't ordered yet, check these first. A chart that's only a little taller than the first one just means doing this again in a few years.
- A top measurement well above where your tallest child is headed. Look for the listed range on the product page, not just the photo.
- A scale that starts low enough for your earliest marks. If the first chart holds baby-era lengths, make sure the new one reaches that far down, or plan to record them in a note.
- Units you want to keep using. Switching from centimeters to inches is fine, but you'll convert every mark once.
- Room beside the lines for writing. Transferred marks arrive with years of dates and notes attached.
- A surface that takes ink cleanly. Cotton canvas with a fabric-safe pen gives crisp lines that don't need touching up.
- Easy to take down and carry. If you'll move again, a single hanging point beats a board screwed into the wall.
Our Canvas Kids Growth Chart ($44) is 100% cotton canvas with a single grommet. Its scale starts at the 6-inch mark so it clears the baseboard, and it comes with a fabric-safe pen, so you can copy a full backlog of marks the day it arrives. You can add a name and pick a font, and a rainbow version at the same price is in our canvas growth chart collection. Allow 7–10 business days for shipping if you're timing the switch around a birthday. Before you order, compare its full length with the top of your current chart so you know it gives you real room to grow.
What do you need for the transfer?
- ☐ The old chart, still hanging if possible (you'll check it against the floor)
- ☐ A metal tape measure; a cloth sewing tape can sag over longer distances
- ☐ A straightedge at least 12 inches long, or a carpenter's square
- ☐ The new chart's pen, or a fine-tip fabric marker you've tested on the hem or back
- ☐ A roll of low-tack painter's tape and a pen for labeling it
- ☐ Your phone, for photos of every mark
- ☐ A mark log on paper or in a spreadsheet (template in Step 1)
- ☐ A clean table as long as the new chart, or the wall spot where it will hang
Step 1: Log every mark before the old chart comes down
Photograph the whole chart first, then each mark up close with the printed scale visible in the frame. If anything goes wrong later, those photos are your backup.
Then go mark by mark and fill in a log. Read each height where the middle of the line meets the scale, rounded to the nearest 1/4 inch. A copy can't be more precise than the pen line itself, so don't chase sixteenths.
Copy every note exactly as written, including anything a child wrote themselves. If a date is missing, write what you know, like "summer before kindergarten," rather than guessing a day.
| # | Child | Date measured | Age | Height (in) | Note beside the mark | Copied? |
|---|---|---|---|---|---|---|
| 1 | Sam (example) | Sept 2024 | 2 yrs | 34 1/4 | "First haircut" | Yes |
| 2 | ||||||
| 3 |
Number the rows so none get skipped, and sort by child, then by date. If Step 2 turns up a correction, cross out the old number and write the new one beside it.
Step 2: Check the old chart against a tape measure
In short: if the old chart hung too high or too low, every reading is off by the same amount, and one quick check catches it.
Pick two marks far apart, one near the bottom and one near the top. Hook a metal tape measure on the floor, not the top of the baseboard, and measure straight up to each line. Compare those numbers to what the printed scale says.
- Both within about 1/4 inch: the printed scale is trustworthy. Use your log as written.
- Both off by the same amount: the chart hung at the wrong height. If it hangs too high, the printed numbers read short, so add the difference to every mark. If it hangs too low, subtract it.
- Off by different amounts: the canvas may have stretched, or the printed scale may not match a tape measure. Measure every mark from the floor and use those numbers instead.
One catch: a floor check only tells you about marks made in the chart's current spot. If the chart has hung in more than one place, see the table further down.
Step 3: Copy the marks onto the new canvas
With a checked log in hand, the transfer itself is mostly careful ruler work.
- Get the new chart's scale true. If you'll mark it on the wall, hang it first, following the maker's directions for how high the bottom sits. Our guide to hanging a canvas growth chart without wrecking your wall covers the one-anchor method. Then hook a tape measure on the floor and confirm one printed line reads correctly.
- Or lay it flat. Marking on a table gives steadier lines and is just as accurate, because you're reading the chart's own scale, not the wall. Weight the corners and let fold lines relax for a day. Check the care label before you iron: some printed canvases shouldn't take heat at all.
- Tape before you ink. Put a small tab of painter's tape at each height, labeled with its row number from the log. Step back and compare the spacing to the old chart. The gaps between marks should look about the same, even if the positions don't.
- Draw each line with a straightedge, square to the scale, using the same length for every mark from the same child.
- Write the date, age and note beside each line. If you'd like to add more than the old chart had room for, these ideas for what to write beside growth chart marks go well past the date.
- Tick off the row, peel the tape, and let the ink dry fully before you roll or hang the chart.
- Measure your child today and add a fresh mark, so the new chart has one that's entirely its own.
Should copied marks look different from new ones?
That's a family choice. Here are the three common approaches.
| Approach | What it looks like | Choose it if |
|---|---|---|
| Copy them plain | Same pen and style as every future mark | You want one clean, even record |
| Add a small symbol | A dot or tiny "c" beside each copied line | You want to see at a glance which marks are copies |
| One transfer note | A single line beside the last copied mark: "Marks below this line copied from our first chart, [month and year]" | You want tidy lines and an honest record |
We lean toward the transfer note for most families. It keeps the chart clean and still tells the story. And if a grandparent wrote the early marks on the first chart, ask them to write the copies too. The handwriting is part of what made the first one worth saving.
What if the old chart is metric, moved or already packed?
Most transfers hit at least one of these. Here's how to handle each without guessing.
| Situation | What to do |
|---|---|
| The old chart is in centimeters | Divide by 2.54 to get inches, then round to the nearest 1/4 inch. For example, 90 cm ÷ 2.54 = 35.4, so draw it at 35 1/2 inches. |
| The chart has hung in more than one home | Trust the printed scale for marks made in earlier homes. Apply a floor-check correction only to marks made since it went up in its current spot, and note which ones in your log. |
| The old chart is already down or packed | Lay it flat and read the printed scale with a straightedge across each line. You can't do the floor check, so write "scale reading" at the top of your log. |
| Early marks fall below where the new scale starts | Write them in a note beside the lowest printed line, such as "Birth length: 20 in, lying down," or keep them on a card stored with the chart. |
| Some early marks were lying-down lengths | Copy them, but label them "lying down." Lengths and standing heights aren't taken the same way, and the label keeps anyone from misreading the switch between them. |
| A mark looks out of order | Copy it as written and add a note like "date unsure." Don't nudge it to look right. If a mark ever worries you, your pediatrician's well-visit records are the ones to check. |
| Two kids shared the old chart | Split the log by child. On the new chart, give each child their own pen color or side of the scale so lines never overlap. |
| Some marks are on a wall or doorframe, not a chart | Same idea, different first step. Our guide to transferring wall pencil marks to a new growth chart covers measuring them before you paint or move out. |
What should you do with the old chart?
Keep it. The new canvas holds the numbers; the old chart holds the original lines, the first handwriting, and whatever smudges came with them. A few good options:
- Store it rolled, not folded. Roll it loosely with the printed side facing out, wrap it in acid-free tissue, and keep it somewhere dry and dark. Hot attics and damp basements are the usual trouble spots. Our guide to protecting a canvas growth chart from fading covers storage in more detail.
- Give it a quieter wall. Hang it in a guest room or a grandparent's hallway as a display of the early years, out of direct sun.
- Keep the log with it. Tuck a copy of your mark log and a few photos inside the roll, so whoever unrolls it years from now knows what was copied, and when.
If the first chart was a gift, let the giver know the marks moved to the new chart. It's a small note, and a nice thing for them to hear.
The whole job comes down to one rule: move the numbers, not the lines. Log every mark, check the old chart once against a tape measure, get the new scale true, and copy each height where the new chart says it belongs. Then measure again, and let the bigger chart start filling in.
Frequently asked questions
Can I trace the old growth chart marks straight onto the new one?
Only if both charts use the same scale and hang at exactly the same height, which is rare. Most charts start their scales at different points, so traced lines land in the wrong place. Read each mark as a number in inches and draw it at that number on the new chart instead.
What pen should I use to copy marks onto a canvas growth chart?
Use the pen that came with the new chart, or a fine-tip fabric marker. Test it on the hem or back first to check for bleeding, and let each line dry before you roll or hang the chart. Everyday ballpoints and some permanent markers can feather into the canvas weave.
How accurate will transferred growth chart marks be?
If you read each line carefully and check the old chart against a tape measure, copies should land within about a quarter inch of the original height. That's close enough that it won't change what the chart shows. More precision than that isn't realistic with hand-drawn marks.
When is the right time to switch to a bigger growth chart?
Good moments are when your tallest child is within a few inches of the top, before a move, or when a new sibling needs room. Switching right after a regular measuring day means your log is complete and the next mark goes straight onto the new canvas.
Can I move marks from a wooden or ruler-style growth chart to a canvas one?
Yes. The method is the same: read each mark as a height, check the old board against a tape measure while it's still on the wall, and draw each mark where the canvas scale shows that number. Rigid boards can be mounted a little high or low just like fabric charts, so the floor check matters just as much.
