Size Guide

Last updated: November 14, 2026

How this guide works

This is a guide to choosing, not a chart of numbers. We do not publish a measurement table on this page. What we can give you is a reliable method: take a garment you already own and like, measure it in two places, and use it as your reference when you pick between sizes.

The method has one advantage over any chart. A chart tells you what a garment measures; it cannot tell you how you like your clothes to sit. The tee you reach for on a Saturday morning already holds that answer.

If you measure and still cannot decide, email support@plantink.shop with the plate you are looking at and how you want it to fit. We reply within 24 hours on business days.

The sizes we offer

The price on the product page updates when you select a size, so the add-on is visible before you add the piece to your cart. The size labels on this page are the same labels you will see in the size selector.

What unisex means here

All Plant Ink apparel is cut in a unisex fit. There is one run of sizes, S to 5XL, and it is not divided into men’s and women’s cuts. In practice a unisex garment is straight through the body, without shaping at the waist.

If you usually buy from a fitted or women’s range, a unisex size with the same letter may sit looser on you than you expect. If you usually buy from a men’s or unisex range, your usual letter is the sensible place to start, and then the measuring step below will confirm or correct it. We do not promise that any size matches the letter you wear in another brand; brands differ, which is why the garment you own is a better reference than the letter on its label.

Measure a garment you own

You need a tape measure, a flat surface, and a garment of the same kind as the one you are ordering: a tee for a tee, a sweatshirt for a sweatshirt, a hoodie for the hoodie. Choose one whose fit you like.

Step 1: lay it flat

Put the garment face up on a table or a bed and smooth it out with your hands. Do not stretch it. Straighten the side seams so the front and back lie on top of each other.

Step 2: chest width

Measure straight across the chest from one side seam to the other, about a thumb’s width below the armholes. Keep the tape level. This single measurement tells you the most about how roomy a garment feels.

Step 3: body length

Measure from the highest point of the shoulder, where the shoulder seam meets the collar, straight down to the bottom hem. This tells you where the hem will fall when you stand, bend or reach.

Step 4: write both down and name the fit

Note the two numbers and the size printed on that garment’s label, and add one word for how it fits you: snug, easy or loose. Those three facts are your reference. If you write to us for advice, include them and we can answer in one reply.

A note on measuring yourself

You can also measure around the fullest part of your own chest with the tape level under your arms. It is a useful check, but a body measurement on its own does not say how much room you like. Use it alongside the garment you measured, not in place of it.

Between two sizes

Most sizing questions we receive are from people who sit between two letters. The right choice depends on what you will be doing in the piece.

Worked example: between L and XL for the garden

Say you wear L in some tees and XL in others, and you want the Tomato Illustration T-Shirt for days in the vegetable beds. Your favourite gardening tee is an XL that you described as easy. You spend those days reaching across a raised bed to tie in stems. Everything in that picture points the same way: choose XL. If the same person wanted the Hoya Illustration T-Shirt to wear to dinner, tucked in, the L would be the better pick.

Worked example: sizing a sweatshirt for layering

You wear M in tees and want the String of Hearts Illustration Sweatshirt for cold mornings in the greenhouse, over a long-sleeved shirt. Measure a sweatshirt you own, not a tee. If you do not own one that fits well, put on the shirt you would layer under it and try a friend’s sweatshirt in M and L. For layering, most people between two sizes are more comfortable in the larger.

When the size is for someone else

Buying a size for another person is the hardest version of this problem, and guessing is how returns begin. A few quieter approaches work better.

• Look at a label. If you can get to their wardrobe or their laundry, read the size on a tee or sweatshirt they wear often, and note whether it looks snug or loose on them.
• Measure it if you can. Two minutes with a tape, following the steps above, gives you a real reference.
• Ask someone who would know. A partner, a sibling or a housemate can usually tell you.
• When in doubt, go one up. A sweatshirt that is a little roomy is still worn; one that is tight usually is not.
• Or choose a piece with no size. The tote bags, the garden apron and the mugs need no size at all. They are gathered under Aprons, Totes & Mugs.

Consider the daughter in Ohio ordering the Sweet Pea Illustration Sweatshirt with Your Garden Name for her grandmother, with “Nana June’s Herb Patch” on it. She knows the name of the patch but not the size. A look at the label of the cardigan on the back of the kitchen chair, or a call to an aunt, settles it. If the guess is still wrong, the sweatshirt can be returned within 60 days with a free return label, personalised or not.

Mugs: 11 oz or 15 oz

The two mugs, the Spider Plant Illustration Mug and the Prayer Plant Illustration Mug, come in 11 oz and 15 oz. The number is the volume the mug holds. The 15 oz adds $3.

The choice is about how you drink. The 11 oz is the size of an ordinary household mug and suits a cup you finish while it is hot. The 15 oz holds roughly a third more and suits a long pot of tea carried out to the potting bench, or coffee with plenty of milk. A tea drinker who refills twice every morning is probably a 15 oz person. If the mug is a gift and you have no idea, the 11 oz is the familiar size.

Tote bags and the garden apron

The two tote bags and the Nasturtium Illustration Garden Apron with Your Name are one size, so there is nothing to select. We do not list dimensions for them on this page. If a particular measurement matters to you, for example whether a tote will take a certain tray for the plant-swap table, email us before ordering and ask.

Fabric and care

The care label in each garment lists its fabric and care. Follow that label when you wash and dry the piece. We do not make statements here about fabric content or about how a garment behaves in the wash, because the label sewn into the garment you receive is the reliable source.

Common sizing mistakes

• Measuring a different kind of garment. A tee and a sweatshirt with the same letter are not the same width. Compare like with like.
• Measuring a garment that is stretched out. An old favourite that has lost its shape gives a misleading number. Pick one that still fits the way it did when it was new.
• Trusting the letter alone. The L in your drawer and an L here are not promised to match. The tape is the better guide.
• Forgetting the layer underneath. If the hoodie will go over a thick shirt, measure with that in mind and lean larger.
• Ordering two sizes to compare, then forgetting the window. You are welcome to order two and return one; the return must be made within 60 days.

If the size is not right

There are two routes, depending on when you notice.

Within 24 hours of ordering

Email support@plantink.shop with your order number, the plate, the size you ordered and the size you want. We can change it before printing. If the new size carries a different add-on, the price changes with it. The Cancel or Change an Order page explains the steps.

After it arrives

You have 60 days to return a piece. We send a free return label, including when the only reason is that the size does not suit. The refund is issued within 7 days of our receiving the return, and you can place a new order for the size you want whenever you are ready. The Returns & Exchanges Policy describes the process, and the Refund Policy covers the money.

The same applies to the personalised plates. A Monstera tee with your name on the collector’s line can be returned for size like any other piece.

Asking us for a recommendation

We are glad to help you choose. To get a useful answer in one reply, tell us:

1. which plate you are ordering, by number or by name;
2. the size on the label of the garment you measured, and how it fits you;
3. its chest width laid flat and its body length;
4. how you want the new piece to fit, and what you will do in it.

Write to support@plantink.shop. For other questions, the FAQs have short answers, the Help Center sorts every support page by situation, and the shop page lists all twenty plates.
