Diane Keaton stands in a bright beach house kitchen in East Hampton, wearing a white shirt and knitted cardigan, peeling vegetables at a wooden kitchen island. The scene is from Nancy Meyers’s 2003 film Something’s Gotta Give, and it has become one of the most copied home interiors in the world—even though nobody had a name for it at the time. The name came later, in 2022, when TikTok creator Lex Nicoleta coined the term coastal grandmother. Since then, the style has gone from an internet joke to one of 2026’s most enduring interior design trends, and a well-chosen poster is one of the easiest ways to capture it. This guide explores where the style really comes from, why it’s taking off right now, and exactly how to create it on your own wall with the right print.
The name is a little misleading. Coastal grandmother is neither about being a grandmother nor about living by the sea. It’s about a feeling: serene, mature elegance, bright rooms, linen, fresh flowers, and a bookcase overflowing with books. It’s the calm of coastal living without seashells and anchors—cultivated, not kitschy. And it’s precisely this combination of relaxed and elegant that has led a younger generation to embrace an aesthetic named after someone’s grandmother. Where austere minimalism often demanded discipline to keep things tidy, coastal grandmother instead celebrates the lived-in and the personal: a poster leaning against the wall, an open book, flowers that have had time to bloom. It’s a style that makes room for everyday life, and that may be the most important reason it has made such a broad and lasting impact.
Quick facts: The term coastal grandmother was coined in 2022 by TikTok creator Lex Nicoleta, inspired by Nancy Meyers films such as Something’s Gotta Give (Diane Keaton) and It’s Complicated (Meryl Streep). The foundation is a neutral palette—soft white, cream, linen, and sand beige—making up 60–70 percent of the room, often with blue-gray accents. Heading into 2026, the style is seen as part of a shift away from cool minimalism toward warmth, texture, and personal expression.
What Defines the Style—and Why It’s Nothing New
Although the hashtag is new, the aesthetic itself is decades old. It draws on American coastal classicism, which film director Nancy Meyers made her signature: spacious kitchens in white and wood, durable furniture with loose slipcovers, stacks of books, baskets, and always fresh flowers on the table. Meyers's homes were never strictly minimalist or cluttered—they struck a comfortable middle ground where everything looked expensive yet effortless.
Visually, coastal grandmother is recognizable by a few recurring features. The walls are almost always white or a very soft neutral shade. The materials are natural: linen, rattan, oak, ceramics and washed cotton. The palette is muted and light, with the sea suggested rather than spelled out – a blue-gray curtain, a striped cushion, a botanical illustration. And everywhere, there are signs of life: books, flowers, a blanket draped over an armchair. It’s a home that looks lived-in and loved, not staged for a photo.
"Coastal grandmother isn’t the sea on the wall – it’s the calm of the sea, translated into linen, light and a botanical poster in muted tones."
Why coastal grandmother is taking off in 2026
The timing is no coincidence. Interior design in 2026 is marked by a clear shift away from the cool minimalism of the past decade – the cold grays, hard surfaces and almost clinical order. Instead, warmth, texture and personal expression are coming to the fore. Coastal grandmother sits right in the middle of this movement: it’s bright and airy like minimalism, but soft, lived-in and full of natural materials in a way minimalism never was.
The color trend points in the same direction. After several years of warm beige, the palette is shifting toward cooler yet still warm neutrals, and the blue-gray tones that define coastal grandmother fit perfectly with this development. It’s not about navy and red like in classic nautical decor, but muted misty shades: mist blue, gray-blue, salt and sand. It’s a palette that’s easy to live with year-round, even far from any coast.
Swedish homes also have a natural affinity for craftsmanship. Our bright, pared-back Nordic design heritage is already close to coastal grandmother – light walls, wood, natural materials. The difference is that the American style allows itself more softness and more layers: more books, more flowers, more textiles. That makes it a pleasant way to warm up a Scandinavian home without giving up the light.
There’s also an emotional reason why a younger generation has been drawn to an aesthetic named after someone’s grandmother. In an age of fast-paced feeds and constant connectivity, coastal grandmother offers a fantasy of a slower, more grounded life – a home where you finish the book, pick flowers and cook in peace. It’s as much a yearning for a way of life as a way to decorate. A poster plays an unexpectedly big role in that fantasy: a serene image on the wall is a daily reminder to slow down, and it costs far less than a renovation.
Tips: Layer the room using the 60–30–10 rule. Let 60–70 percent be light neutrals on the walls and large surfaces, about 30 percent natural materials such as wood, rattan and linen, and save the final ten percent for a muted blue-gray or sage green accent – ideally in the very poster you choose as a focal point.
Coastal grandmother, room by room
In the living room, the sofa is the heart of the space. A light-colored sofa, preferably with removable, washable covers, is complemented by a large plant, a stack of books, and a muted poster above it. Avoid glossy surfaces and sharp contrasts; everything here should feel soft. A botanical print or a serene seascape in 50x70 above the sofa sets the tone without shouting. Our collection of botanical posters includes serene plant studies made for this style.
In the bedroom, layering is key. White and sand-colored linen bedding, a striped blanket, and one or two nature-inspired posters above the headboard create that characteristic peaceful feeling. Stick to two or three closely related tones for a restful rather than busy result. A diptych of two floral prints works beautifully above a double bed.
In the kitchen and dining area, the style gets to show its love of all things living. Fresh flowers on the table are a signature, and a poster featuring citrus, herbs, or a floral still life brings that feeling to the wall. Here you can dare to use a little more color—a muted yellow or sage green—as long as it stays within the light overall palette. Browse our collection of floral prints for designs that fit the bill.
The entryway and work nook benefit from the same recipe on a smaller scale: a single well-chosen poster in natural tones, a mirror that reflects the light, and a basket for practical storage. If you want to bring the sea in more literally without veering into cliché maritime style, serene photographic art featuring the coast, dunes, and mist is an elegant choice.
A poster rarely does the whole job on its own, and it’s the interplay with the rest of the room that makes the difference between a successful coastal grandmother look and one that feels unfinished. Let the artwork be accompanied by the elements the style is built on: a ceramic vase with seasonal flowers, a stack of books with the spines facing out, a basket made from natural materials, and a linen or washed-cotton textile. Place a green plant near the poster’s subject so the living greenery and the nature depicted in the artwork enhance each other. Think about lighting, too: warm, soft light from a couple of low-level lamps flatters both the artwork and the muted tones far better than harsh overhead lighting. It’s in these layers, rather than in a single expensive piece of furniture, that the feeling of effortless elegance really takes shape, making this style especially easy to build step by step on a small budget.
Motifs, format, frame, and color that define the style
The choice of motif matters more than anything else in getting the look right. Four families of motifs work especially well for coastal grandmother: botanical illustrations and pressed flowers, serene seascapes and coastal landscapes, light still lifes with flowers or fruit, and calm abstract art in misty tones. Avoid strongly graphic motifs, saturated primary colors, and anything that feels too formal or too literally nautical. It should suggest, not illustrate. Think of the image as a window onto something serene rather than an exclamation mark; the calmer the image, the more it does for the whole room. A good rule of thumb is that a coastal grandmother-style poster should lower your pulse when you look at it, not raise it. Among our nature prints, you’ll find landscapes in just the muted palette the style is built around, and if you’re looking for something more restrained and calm, minimalist prints in neutral tones work well too.
When it comes to format, the style benefits from generous sizing for calm motifs. A large poster in 50x70 or 70x100 with a serene image fills the wall without feeling imposing, as the calmness of the image balances its size. If you’d rather have several smaller images, a pair or trio in the same muted palette works better than a scattered gallery wall - coastal grandmother is composed, not cluttered.
The frame should be understated and natural. Light wood such as oak, a warm oak veneer, or a simple white frame best suits the style; black frames and shiny metal frames feel harsher and break the mood. An off-white mat enhances the airy feel and draws attention to the artwork. In terms of color, stick to a light base and let the poster’s muted blue-green or sage-green tones become the room’s accent. To understand how this style relates to other warm styles, read our guide to Mediterranean style, which shares coastal grandmother’s love of light and natural materials but with a warmer, more southern palette.
Coastal grandmother is fundamentally a biophilic style - it brings nature into the home through materials, flowers, and motifs.
